Do not have Stanza.getExtension(String, String) return a generic type

Browse source 
Returning a generic would allow for

List<ExtensionElement> list = stanza.getExtension("foo", "bar");

to compile (Note the we are calling getExtension(), not
getExtension*s*()).

Users are encouraged to use the type safe getExtension(Class<? extends
ExtensionElement) variant instead.

Fixes SMACK-825.
