Dont' deleted the queue after testing (using delQueue = True), it takes several seconds to be done and it does not impact any other test
Give the consumer 2 seconds before asserting consumed messages
 * Validate jasmin.protocols.smpp.test.test_smpp_client.LongSubmitSmErrorOnSubmitSmTestCase:
     After modifying the protocol behaviour in endOutboundTransaction (smpp.twisted.protocol) where no more errbacks are called on errors because
     we need to log any error returned from the SMS-C, the long SMS handling behaves differently and must be realigned
 * Validate jasmin.protocols.smpp.test.test_smpp_client.SubmitSmIncorrectlyBoundTestCase.test_submit_sm_receiver_failure which was also impacted as
     the first point
Added tests for:
* Long SubmitSm (through http api)
* Long SubmotSm errors (through http api)
* Incorrectly bound SubmitSm
