Facebook: Fix support for "new" group chats (dirty changes)

This commit is just quick workaround for group chat changes, where Facebook stopped using "id.XXX" ids, and instead use just "XXX" fbids. And for old existing chats tolerates old type, but for new forces this new format.

I don't know how that, or changes in this commit, affects classic conversations, but in any case this commit should be cleaned and integrated better. Perhaps rewrite whole uses of "ids" to "fbids" everywhere.
