mod_rest: Add special handling to catch MAM results from remote hosts
Makes MAM queries to remote hosts works.
As the comment says, MAM results from users' local archives or local
MUCs are returned via origin.send() which is provided in the event and
thus already worked. Results from remote hosts go via normal stanza
routing and events, which need this extra handling to catch.
This pattern of iq-set, message+, iq-result is generally limited to MAM.
Closest similar thing might be MUC join, but to really handle that you
would need the webhook callback mechanism.
