aacparse: Reset parser when we have caps without codec_data

This ensures the detection (and proper downstream caps settings) will
actually happen when we have new incoming caps without codec_data.

This was easily triggered by streams from matroskademux which initially
provided caps with a constructed codec_data, but then pushed new caps
without the codec_data once it detected the stream was adts.
