post an error in room if a user sends a message in a bridged room, but the bridge doesn't/can't send the message

I sent a message via riot to a bridged slack room at 23:53, but the bridge didn't forward to slack and didn't error out.

Here are the logs from mx-puppet-slack

Jan-29 23:53:28.890 [bot-sdk-Appservice] info: Processing event of type m.room.message

Jan-30 00:53:29.000 [RoomSync] info: Maybe leaving ghost @eric:eric.nova.chat from !YQSUYdeTAk:eric.nova.chat

but no message was sent to slack.

Unfortunately, due to the nature of things, each protocol implementation will have to do that on their own. mx-puppet-discord does this already, though

Ok, I'll close this and open in each protocol if that's better (just to track)
