Removed obsolete test_get_or_create_raises_IntegrityError_plus_traceb…

…ack() test.

This test was added in 31b1cbc, but is
no longer needed, as the fix was reverted in
746caf3 without any consequences, so
it now tests Python behavior rather than Django. Moreover, traceback
introspection is problematic for .pyc-only installations.
