hangouts groups support with purple-hangouts 0.54 & 0.56

[evgenyh]

Using this backend all works fine escept groups.
when someone adding me to group , spectrum2 not being notified on this at all, so no new entry in roster is being created.
And then when someone sending messages to such group I can only see entries in log like this :
NetworkPluginServer: handleConvMessagePayload: No conversation with name UgyOoS6njI6J-EnJN9p4AaABAQ

• tested with purple-hangouts 0.54 & 0.56

thanks

@evgenyh group chats from purple-hanouts does not work entirely or suport is just limited?
I have prosody server with spectrum2 and purple-hangouts and I am struggling to set up hangouts group chat support.
Sorry for necrobumping.
