Fix model test path typo uncovered in previous commit.

Because of the expanding whitelist for test filters, this test ended up
running the tests on lines 4 and 9 in the post test even though the path
wasn't right.

Happened incidentally because the same line numbers were used in both
account and post test.

Add the .rb line so the file is required correctly and the filters are
applied.
