core.moduleapi: Filter out unrelated direct replies to module:send_iq This is primarily something that happens with an internal query to mod_mam, which calls origin.send() several times with results, leading to the first such result being treated as the final response and resolving the promise. Now, these responses pass trough to the underlying origin.send(), where they can be caught. Tricky but not impossible. For remote queries, it's even trickier, you would likely need to bind a resource or similar.
