Refactor-rename doesn't change occurences in other modules

Sometimes that's also the case within a module, but there's already an issue for that ( #657).
This here hits me every time I rename something that's used from e.g. Main.hs.

This is a difficult issue. It seems to be non-deterministic... and probably depending on the size and structure of the project
