Merge #768

768: Sort assists by the range of the affected element r=matklad a=robojumper

Closes #763.

https://github.com/rust-analyzer/rust-analyzer/blob/3be98f2ac93b278828e76eb813bdd8033f647b12/crates/ra_assists/src/lib.rs#L233-L236

This could be made more robust by a) adding a way to identify actions by things other than their label and b) allowing arbitrary actions to appear in the list as long as the tested actions are there in the correct order. Let me know if I should do any of that.
