@PiotrZSL, thank you for pointing out better naming pattern for diag-messages, would use it in the future.

1. Created new warning and fix-it messages.
2. Renamed check.
3. As for now, my check can support any type that will have `reset` method, this include `std::optional`. Maybe a more general approach would be to detect overlapping methods with classes that are returned via `operator*` and `operator->`. However, if some method is called on main object and there is no equivalent of `= nullptr` I don't know how user can fix such warning.
