STOMP: modernize Python test suite

 * Upgrade to stomp.py 4.1.24 to gain Python 3.9 compatibility
 * Adjust to modern client/plugin disconnection delay
 * Remove tests that are not really possible to test with
   a regular well-behaved client (missed heartbeats)

(cherry picked from commit 3c38b42)
