Inviting a non-contact matrix puppet of whatsApp user to a new room don't work as expected #284

When i tried to invite the matrix puppet of a whatsapp contact to a room ( @whatsapp_xxxxxxxxxxxx:matrix-home-server.org ) , the puppet didn't get properly invited.

Some context for this behavior:

  1. the contact was completely new to the whatsapp bridge and was not on the phone's contact list. 2.the contact was not on matrix as well.
  2. If i use the !wa pm --force ... phone_number to initiate the chat, everything works as expected.

I investigated the issue here and i found out that this was because the bridge bot was silently receiving the error "SynapseError: 403 - Application service has not registered this user" and thus, aborting the process of creating the private portal.

I located the issue on the HandlePuppetInvite handler when it was checking the members of the room ( method joinAndCheckMembers () ). I suppose since the puppet was recently created, it was not yet registered on matrix.

I don't know if this was an intentional behavior, but i patched the code and now it's working perfectly.

If you think it's valid to provide a PR, let me know !

I think i have an equivalent issue but in the other way.

An unknown contact send me a message on WA and the bridge has crashed after create the room and invite me in.
