Remove temporary bail-out on something that crashed jack often.

Rationale:
Nightly has switched to dx testing, so we can safely remove
this bail-out in favor of more coverage. Not sure if jack
is still under development, but I hope this issue will
eventually be fixed still.

Test: nightly fuzzing
Bug: 28862040
