Merge #3553

3553: Completions do not show for function with same name as mod r=matklad a=JoshMcguigan

fixes #3444 

I've added a test case in `crates/ra_ide/src/completion/complete_path.rs` which verifies the described behavior in #3444. Digging in, I found that [the module scope iterator](https://github.com/JoshMcguigan/rust-analyzer/blob/ba62d8bd1ce8a68b8d21aaf89ae1ea6787f18366/crates/ra_ide/src/completion/complete_path.rs#L22) only provides the module `z`, and does not provide the function `z` (although if I name the function something else then it does show up here). 

I thought perhaps the name wasn't being properly resolved, but I added a test in `crates/ra_hir_def/src/nameres/tests.rs` which seems to suggest that it is? I've tried to figure out how to bridge the gap between these two tests (one passing, one failing) to see where the function `z` is being dropped, but to this point I haven't been able to track it down.

Any pointers on where I might look for this?
