Thiago Santos 3f2bea0d47 tests: baseparse: add test for reverse playback on passthrough
Baseparse stores buffers for reverse playback to push on the next
DISCONT, the issue was that it wouldn't ever check for a discont
on passthrough mode as it skips all real parsing. This test
was create to verify this issue and prevent it from happening again
