Merge #4421

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

Fixes #4188 

Yet again, it looks like although the code in 
https://github.com/rust-analyzer/rust-analyzer/blob/da1f316b0246ce41d7cb8560181e294089f06ef3/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()`.
