Removed xfail from app submission tests and added environment parameter of MockApplication
The parameter is used when setting the submission id and security code, I couldn't use the same submission id for both dev and stage. The staging submission id was generated separately.

Remove xfail from test_user_can_go_back_from_settings_page().
The test was xfailed for the reason mentioned in the following comment [1]. I have checked the latest builds and in most of them the test XPasses. In the situations where it fails it is for other reasons than the one mentioned in #381.
I removed the xfail so that the job fails if the test encounters other errors.
