Fix flaky test by slightly changing its setup.

The test is flkay (2/1000 runs) because the decoder initialization
before and after the seek are not perfectly deterministic. I couldn't
find a way to make them deterministic, so slightly chaning the test
setup instead. The test setup change doesn't affect the scenario being
tested.
