Fix Git over HTTP spec

* The spec has 7 failures at this point
* Specify rendered error messages
* Render the GitAccess message rather than “Access denied”
* Render the Not Found message provided by GitAccess, instead of a custom one
* Expect GitAccess to check the config for whether Git-over-HTTP pull or push is disabled, rather than doing it in the controller
* Add more thorough testing for authentication
* Dried up a lot of tests
* Fixed some broken tests
