mod_archive: switch from/to The XEP-0136 is not very explicit about the meening of <from> and <to> elements, but the examples are clear: <from> means it comes from the user in the 'with' attribute of the collection. That is the opposite of what is currently implemented in that module. So for better compatibility with complient clients, this switch the 'from' and 'to' fields
