Expose the range of the decl's name

Fixes #230

[matklad]

Could we add a high-level rename test here as well?

[kjeremy]

Hm. Do we have tests for LSP handlers?

[matklad]

No, but I think we should test it on the analysis layer, not on the LSP layer. That is, we can move the bulk of handle_rename into ra_analysis, and then write a test for it there.

@kjeremy do you want someone to make this change, or are you willing to update it yourself?

[kjeremy]

Feel free to make it!

#375 supersedes this - I think we can close.
