Bug 1033808 - Automatically make bugzilla-import task unavailable based on criteria

I don't recall whether we specifically discussed that or not, but it is true that I prefer to mock as much as I can. Having said that, after doing all this mocking I found myself wondering if I'm really testing what needs to be tested. I agree that this is a valid unit test of the method logic, but so many pieces are mocked out that it might fail to find problems at a slightly higher level. I will look into using some "real" objects in the test.
