    Fixed the tests in test_models.py

    The tests were failing when run as a single module
    for the test-module trove.tests.unittests.mgmt.test_models

    There were two reasons of failure:
    - test_models.TestMgmtInstanceDeleted.test_show_deleted_mgmt_instances fails
      because this test expects some deleted/active instances to pre-exist.
    - other tests were failing because MockMgmtInstanceTest.build_db_instance
      was trying to create test-instances using a non-existent version.
