rerunning glue tests with repo_test having order locked

hopefully this will resolve the following intermittent error:
test_has_package?(GluePulpRepoRequiresSyncTest) [/home/travis/build/Katello/katello/test/glue/pulp/repository_test.rb:229]


minitest by default runs test in random order and vcr by dy default
expects requests that match each other to be ordered when they were played, 
so lets force the ordering for this test to see if it helps this intermittent test failure
