AMQ-6809 Fix issue where stream message getBytes returned wrong value 

StreamMessage implementation should return zero when the full value of a
written byte array has been consumed before then returning -1 on the
next read.  Ands fix and additional testing of ActiveMQStreamMessage
(cherry picked from commit 61d3231d36)
