frames: do not rely on FRAME_STREAM_ID

As it is not always the first frame to be created :
if it is not enabled, it does not get created, and other enabled
frames may be created first. see use of FrameConfigTypeIsEnabled

This resulted that this other frame got its length updated
on stream end, which led to false positives.

Resorting on FRAME_STREAM_TYPE is more consistent.
