multiple-pause-resume: skip PAUSE/RELEASE test on Echo Reference pipeline

Smart Amp playback pipeline and Echo Reference capture pipeline are
interdependent, so random pause/release 1 or 2 of them will cause an
invalid bug #4434. This patch filters out the Echo Reference capture
pipeline for the pause/resume test, it's not a valid use case.
