context.elevated() should use copy.deepcopy()

Currently context.elevated is just doing a copy.copy(self).
This needs to be changed to use copy.deepcopy so that the
list reference is not shared between objects which leaves
the possibility of an admin role leak.

This fix changes context.elevated use copy.deepcopy.
