Import item suggestion should come before did-you-mean suggestion

I've hit this case a few times now: I do some regex-based mass renaming that only works for expressions, not imports, then manually clean up the old broken import and want to import the new thing using the import suggstion whereever a new name needs importing.

This usually works fine, until there is an item already in scope with a similar name to what I need to import. My muscle memory then sometimes leads me to apply the first suggestion of "there's a thing with a similar name in scope, did you mean that?" when that is not what I want.

I think when there is an exact match for an unresolved name, the suggestion to import it should be higher up in the list of suggestions than pretty much anything else.

Start by tracing rust-analyzer's completion suggestions for unresolved names, focusing on how import suggestions are ordered against did-you-mean suggestions. Reproduce the case with an exact import match and a similar in-scope item; done means the exact import suggestion appears first.
