keyboardcomposer destroy fix and cleanups - We were destroying KeyboardComposer a little too much. Fortunately, we weren't passing the right number of arguments, so this was merely an error. - About the TODO comment removed: we don't need to use combine_dict since Submaster logic will be changed entirely when we/if we move to a SubServer world and keyboard composer will not be the wiser.
