4421: Find references to a function outside module r=flodiebold a=montekki

Fixes #4188 

Yet again, it looks like although the code in 
da1f316b02/crates/ra_ide_db/src/search.rs (L128-L132)

may be wrong, it is not hit since the `vis` is `None` at this point. The fix is similar to the #4237 case: just add another special case to `Definition::visibility()`.
