Tests that use EnvironmentManager.reset_environment fail sporadically with the following:

2016-03-16 16:33:50.509 | nailgun/test/base.py:999: in reset_environment
2016-03-16 16:33:50.509 | self.tester.assertEqual(resp.status_code, expect_http)

commit 3e4da833e5e52064615059decce1b58c4e333ea9

    Accept both 200 and 202 if no particular result is awaited

    When deferred task is started successfully API can return either 200
    or 202 depending on task status. So, we should not rely on particular value
    if caller did not set it (comparand) explcitly.
