 Tests: offline buffering - sending messages while disconnected

 1. send some messages while disconnected, check that they are sent
 2. repeat test 1 using serverURIs
 3. repeat test 1 using auto reconnect
 4. repeat test 2 using auto reconnect
 5. check max-buffered
 6. check auto-reconnect parms alter behaviour as expected

 Tests: automatic reconnect

 - check that connected() is called
 - check that reconnect() causes reconnect attempt
 - check that reconnect() fails if no connect has been previously attempted
