Eric House 863a54bfe1 Once received, nuke invite on mqtt broker
To prevent deleted games' ghost invitations from remaining as
persisted on a topic and so being received over and over, have
recipient of invitation send an empty message on the same topic to
remove them. Any message sent once the game start would have replaced
the invitation, but sometimes if the sender is deleted at the right
time there's none.
