Analysis API: Fix issues related to implicit invoke calls:

- Correctly set explicit receiver value.
- Restore original function call from FirImplicitFunctionCall (i.e.,
calls implicitly resolved to `invoke`) to get the correct name for
getting all candidates.
- Collect candidates at all tower levels.

Also make order of candidate calls in tests deterministic.
