Rework MUC reflected message filtering

Reflected messages can't be filtered by nick only otherwise you might
ignore messages comming from you on another devices.

Consequently we maintain a list of sent messages id in mucwin.
To be sure the id will be correctly reflected we use the origin-id
stanza.
