    Rest back objects for test_objects

    When test_objects run, it will load some dummy objects such as Foo
    etc, the problem is that Foo did not have '_type' field, so the
    unit test will be failed.

    This patch was resetting objects for all test cases in test_objects.

    Closes-Bug: #1413144
    Implements part of bp increase-test-coverage
