startchat: fix contact disappearing from search once a DM exists#288
Merged
Conversation
Messenger DMs are created as ENCRYPTED_OVER_WA_ONE_TO_ONE (type 15), but SearchUsers only surfaced plain ONE_TO_ONE results, so a contact vanished from Start New Chat once a DM existed. Relax the SearchUsers filter to accept all 1:1 thread types via IsOneToOne(). Make GetFBID() return OtherUserId when set, falling back to ResultId for any 1:1 thread type.
