Title: Remove `BackwardCompatibility` module from `FilterManager` for rspec-3.0.

This is for https://github.com/rspec/rspec-core/issues/1197. I am not sure if there are more things that need to be done. I assumed that since we are removing `BackwardCompatibility` module, it was ok to remove the specs that were testing deprecation messages were shown correctly.
