[Search][POD::UserInterface] Use specification:derepecated? instead of the remove presenter:deprecated?

* 'master' of github.com:luisdelarosa/CocoaPods:
  Added 8 tests for issue #1489, one of which is failing. The failing test reproduces the issue that @jomnius reported with the < version operator. One of the passing tests checks the question that @alloy asked about using ~> with a pre-release version. The other passing tests verify correct behavior with the other version operators when dealing with pre-release versions.

There were conflict in the merge, created a patch and a applied it to a new branch.
