The encryption keys attached to an audio CMSampleBuffer were lost during the
CP->GPUP serialisation.
This preventing the audio stream from being successfully decoded.
While the `sinf` box was correctly attached to the CMSampleBuffer's extensions
the `CommonEncryptionTrackEncryptionBox` was only attached for video samples.
We amend createFormatDescriptionFromTrackInfo so that it handles both audio and
video
content in the same way.
Amend existing test which was incorrectly succeeding.
