Remove deprecated smart proxy scopes
The code was deprecated in 1.5 stable so it was enough time to migrate to with_features scope.

Btw the reason why this should be removed is that it causes issues if some plugin has SmartProxy extensions that gets loaded during environment start, e.g. rake db:migrate. It loads SmartProxy model which tries to load Features but the table does not exist at this point so it fails.
