Mark two test methods public so they can be mocked

Without this, the mocked version looks like it's calling
the default implementation (which immediately fails due to
a bunch of null fields) - with this it just returns null.

I would ultimately like to stop mocking out the controller
and instead use a mocked package manager (which there is
already some set up to do). But in the meanwhile, this at least
gets the test passing.

Test: Checked the test passes.
