Due to the refactoring of TestObjectController (related-change),
all of BaseTestECObjectController test methods are not being
needed to be unpatched because they are expected to run for test
setup-ed policies.
This patch works for items as follows:
- Move part of setUp/tearDown routines at BaseTestObjectController
needed by only TestReplicatedObjectController which affects
patch_policies
- Remove all unpatch_policies from BaseTestECObjectController
- Set up self.ec_policy to avoid to set policy index and
retrieve the policy for each test method.
The reason why I didn't squash this up to the related parent patch is
to clarify what was changed at those patches. The parent is for just
clustering the tests for each test class and this one attempts to
improve.
