Test was added in 5495c2090a to exercise a
previous version of the hotfix-workaround of not allowing seeking back.
Now that the hotfix-workaround also encompasses seeking *forward*, which
breaks another 100 tests, thus requiring the hotfix-workaround to be
turned off for tests, this situation is just completely out of
control. So I'm just removing the test because ugh.
If we are going to continue to let the underlying clock process frames,
there needs to be a bit of lenience to allow the backwards seek on
resume (to play back over the freq ramp period).
The test is meant to be ensuring we don't skip the full offset amount,
so div10 seems pretty safe.
