Diff of `rspec-mocks` to remove circular dependency. Could be a problem if another rspec library calls into mocks then the line returned would be in the that library. This would be consistent with the behaviour that was here before `CleanCaller` was introduced though, and presumably if other libraries want to remove themselves from a trace that'…
