Prepare for breaking change in package:http

The `url` argument is changing from `Object`, accepting either `String`
or `Uri` at runtime, to `Uri` for better static help.
dart-lang/http#507

- Switch to using `Uri` for requests. Where sensible push this type into
  the signature of the surrounding method.
- Make some updated method private where they were unnecessarily public
  which makes it harder to have confidence when looking for usages.
  Rename a method with an unnecessary `get` name.
