unref message when fail to set_notify or when not completed.

Hey folks,

Regarding edbus, I believe that when sending a message, if it fails to
set_notify, it should cancel and unref the pending message. Another
thing, if the pending call doesn't complete, it should free data and
unref it too, right?

I'm attaching a small patch to fix it.

Please, somebody take a look at that when have some time.

Thanks,
