Fix flaky test failure - Githubissues

Reproducer:

py.test test_app/tests/ -k "test_get_system_user_create_raises_exception or test_get_role_definition"

Without this patch, it fails with:

=========================================== short test summary info ===========================================
FAILED test_app/tests/rbac/api/test_rbac_views.py::test_get_role_definition - AssertionError: assert {'local.view_inventory', 'local.change_inventory'} == {'aap.view_inventory', 'aap.change_inventory'}

  Extra items in the left set:
  'local.change_inventory'
  'local.view_inventory'
  Extra items in the right set:
  'aap.view_inventory'
  'aap.change_inventory'

  Full diff:
    {
  -     'aap.change_inventory',
  ?       ^^
  +     'local.change_inventory',
  ?      +++ ^
  -     'aap.view_inventory',
  ?       ^^
  +     'local.view_inventory',
  ?      +++ ^
    }

With this patch, it passes. The test test_get_system_user_create_raises_exception was leaving around a modified INSTALLED_APPS for the rest of the test run.
