generic_inline_admin test fails when run with all tests

[Karen Tracey]

Alone, the new generic_inline_admin test (r9412/r9413) runs fine. However when the whole test suite is run it's failing. From the buildbot logs:

For the record it appears you can isolate things down to running admin_views and generic_inline_admin tests together that cause this breakage.

[Karen Tracey]

Brian -- I'd like to commit the fix I just attached to #9076, but don't want to interfere with this one (which I ran into when running the test suite for the #9076 fix), so I'm holding off. If you think the #9076 fix is OK regardless, let me know and I'll check it in. I would like to get it in for 1.0.1 since it can cause mysterious errors for people following the tutorial, plus results in extra individual queries for each inline object on a page. The test does run fine with the fix when run individually.

[Karen Tracey]

I think the problem is the fixtures for the new test assume a content type id of 13 for the episode content type. The admin_views test (for one) loads other fixtures which change the content type id for episode.

[Karen Tracey]

I think the answer is to create the content in the test setup instead of loading it as a fixture. That works for running admin_views and this new one together...trying for the whole test suite now...

(In [9438]) Fixed #9592 -- Create data for the generic_inline_admin test during setup instead of via a fixutre since it uses a content type id which will vary depending on what other tests have been run.

(In [9439]) [1.0.X] Fixed #9592 -- Create data for the generic_inline_admin test during setup instead of via a fixutre since it uses a content type id which will vary depending on what other tests have been run.
