Tests: fixed reading QUIC streams on Perl < 5.24.
The parse_stream() routine has had a missing explicit return if there were no
streams received. In Perl < 5.24 this used to return no value, or an empty
array in the list context. In modern Perl this returns an empty value, or an
array of 1 element, which made the check for last index of the returned array
work rather by accident.
The fix is to return explicitly and to check the array size in callers instead.
