Merge #460

460: Name resolution fixes r=flodiebold a=flodiebold

Found two problems:
 - use tree desugaring lost the prefix if the path had just one segment (e.g. in `use foo::{bar, baz}`)
 - when resolving imports across source roots, it actually used the name of the segment from the other source root... so e.g. in `use ra_syntax::foo` it'd map `ra_syntax` to the import instead of `foo` :smile: 

Both of these are one-line fixes, most of this is making it possible to write tests with multiple source roots.

I also left in debug logs for the name resolution, in case it turns out there's still more to fix ;)
