It looks like the most nua includes the SIPTAG_EVENT() with the
nua_r_subscribe/nua_r_unsubscribe callbacks only in some corner cases.
Looks like a bug, I'll fix it.
However, the stack does not keep around a copy of event header after
the subscription has been destroyed. In other words, if the stack has
received the final NOTIFY (and responded to it) before the final
response to the un-SUBSCRIBE request is received the o is NULL in
nua_r_unsubscribe.
