Empty unacknowledgedStanzas when 'resumed' is received

Browse source 
by changing

stanzasToResend.addAll(unacknowledgedStanzas);

to

unacknowledgedStanzas.drainTo(stanzasToResend);

Also use sendStanzaInternal to call the callbacks, which also requires
the smEnabledSyncPoint to got signaled.

Fixes SMACK-700. Thanks to Juan Antonio for reporting this.
