New stanzas sent directly after stream resumption might have been added
to unacknowledgedStanzas before the old unacknowledged stanzas
are resent. This caused new stanzas to be sent twice and later led
to a StreamManagementCounterError.
Fixes SMACK-786
by implementing a new logic how the messages are retrieved.
Previously in case the node list has exactly one item, the method
would perform an unnecessary call to nextResult() causing a delay.
Fixes SMACK-785.
Remove the "if (!joined) return" guard in leave() this allows to
resync the instances state with the real world state in case they ever
get out of sync.
Also call userHasLeft() in even if leave() throws and in certain
situations if destroy() throws.
Thanks to Дамян Минков and Ingo Bauersachs for pointing this out.
by calling String.equals() on the constant string and not on the
return value of parser.getName().
Also perform the access to 'parser' on a different LOC than
equals(). This should help debugging things like

A stanza with <error><text>Some text</text></error>, i.e. without a
xml:lang attribute, did not return the value 'Some text' in
getDescriptiveText().
Insert the empty string as key when the attribute is not present while
parsing the xml. When writing, omit the attribute if the key is the
empty string.
Previously StanzaListeners and Collectors where able to receive IQ of
type 'get' or 'set' (i.e., IQ requests) when no IQRequestHandler was
registered. By moving the 'return' statement one level down, even
listeners/collectors won't receive them.
