fix: remove unused import

fix) update broken links in guide.md

Hi, I Just fixed some broken links in `guide.md`.

In most cases, it is not connected by an old version (expecially `guide-2019-01`) of the link, so I made some modifications.

Thanks for your time :)

fix: disregard type variable expectation for if expressions

Fixes rust-lang#13522

As [the comment](https://github.com/rust-lang/rust-analyzer/blob/8142d1f606dc2e52b1d2b8992671e2bd73379f28/crates/hir-ty/src/infer.rs#L1087-L1090) on `Expectation::adjust_for_branches` explains:

> If the expected type is just a type variable, then don't use an expected type. Otherwise, we might write parts of the type when checking the 'then' block which are incompatible with the 'else' branch.

Note that we already use it in match expressions. I've added tests for them too nevertheless.

This reverts commit 319611b.

feat: show signature help when calling generic types implementing `FnOnce`

This queries chalk for the `FnOnce` impl of callees and takes argument and return types from there, making generic `Callable`s available to the IDE. This makes signature help work for them, and potentially allows other features to take generic callables into account in the future.

fix: make custom expr prefix completions to understand refs

Possible fix of rust-lang#7929

While reviewing the postfix completion code I saw that while calling `add_custom_postfix_completions` we were doing it under the part where reference was not taken into consideration, but as we are only adding postfix completions with `Expr` scope ( [source](https://github.com/rust-lang/rust-analyzer/blob/ba28e19b7838e3ad4223ae82d074dc3950ef1548/crates/ide-completion/src/completions/postfix.rs#L272) )

I shifted the `add_custom_postfix_completions` call to part where references are considered

I am not sure if this is the correct fix or I am understanding the problem exactly but this small move seemed to have fixed the issue :)

feat: add config for inserting must_use in `generate_enum_as_method`

Should fix rust-lang#13312

Didn't add a test because I was not sure on how to add test for a specific configuration option, tried to look for the usages for other `AssistConfig` variants but couldn't find any in `tests`. If there is a way to test this, do point me towards it.

I tried to extract the formatting string as a common `template_string` and only have if-else for that, but it didn't compile :(

Also it seems these tests are failing:

```
test config::tests::generate_config_documentation ... FAILED
test config::tests::generate_package_json_config ... FAILED
```

Can you also point me to how to correct these 😅  ( I guess there is some command to automatically generate these? )

scip: Generate symbols for local crates.

Consider something like:

```
// a.rs
pub struct Foo { .. } // Foo is "local 1"

fn something() {
    crate::b::Bar::new() // Bar is "local 1", but of "b.rs"
}

// b.rs
pub struct Bar { .. } // "local 1"
```

Without this there's no way to disambiguate whether "local 1" references "Bar" or "Foo".

internal: Migrate `ide_assists::utils` and `ide_assists::handlers` to use format arg captures (part 1)

This not only serves as making future migration to mutable syntax trees easier, it also finds out what needs to be migrated in the first place.

~~Aside from the first commit, subsequent commits are structured to only deal with one file/handler at a time.~~

This is the first of 3 PRs, migrating:

Utils:

- `gen_trait_fn_body`
- `render_snippet`
- `ReferenceConversion`
  - `convert_type`
  - `getter`

Handlers:

- `add_explicit_type`
- `add_return_type`
- `add_turbo_fish`
- `apply_demorgan`
- `auto_import`
- `convert_comment_block`
- `convert_integer_literal`
- `convert_into_to_from`
- `convert_iter_for_each_to_for`
