Add STREAM_START/STREAM_STOP for transactional messages during decoding.

Browse Source 
In test_decoding module, when skip_empty_xacts option was specified, add
stream_start/stop for streaming transactional messages. This makes the
handling of transactional messages stream consistent irrespective of
whether skip_empty_xacts option was specified.

Commit 26dd0284b9 made a similar change for non-streaming messages but
forgot to update the streaming cases.
