core: re-add Stanza.getExtension(String, String) and mark deprecated

Browse source 
This method was removed with 07da9ffb4 ("Do not have
Stanza.getExtension(String, String) return a generic type"). In order
to aide migration to the newer API, this commit re-adds the method and
marks it as deprecated.
