Only send SM ack requests when connected

we will automatically request one ack for every packet that was send

Also remove unnecessary smEnablededSyncPoint.wasSuccessfully() check

s/smEnablededSyncPoint/smEnabledSyncPoint/
Make the AfterXStanzas constructor public
Add convenience method to AfterXStanzas
