Buggy autocomplete for relative local imports

[maegul]

Describe the bug
Autocomplete is providing incorrect options when importing from local directories with a relative import.

At first, only the already imported top-level import is listed as an option. Then, once the first character of any of the actual sub-directories or modules is typed, the autocomplete will refresh with appropriate options.

The issue is that one cannot lazily rely on autocomplete for writing relative imports.

I'm using pyright in sublime text, but the issue is reproducible in VS Code. See sublimelsp/LSP-pyright#76 (comment)

See screenshots below for demonstration.

Since this isn't a core type checking issue, I'm going to transfer it to the "pylance-release" repo so it gets the attention it deserves there.

I shouldn't have been so quick to assume this was a bug in the completion provider. It turned out to be a bug in pyright's parser. It tries to provide hints to the completion provider in certain error conditions. In this particular case, it wasn't providing the right hint that the partially-completed package name ended in a dot.

Thanks for reporting the problem. It will be fixed in the next release.
