acb7d7df5a [misc] add test cases for the validation of the callback argument 
When the user provides a function as last argument for socket.emit,
 socket.io will flag this as an RPC and add a cb as the last argument
 to the client.on('event', ...) handler on the server side.
Without a function as last argument for socket.emit, the callback
 argument on the server side is undefined, leading to invalid function
 calls (`undefined()`) and an unhandled exception.
The user can also provide lots of other arguments, so the 2nd/3rd ...
 argument is of arbitrary type, again leading to invalid function calls
 -- e.g. `1()`.

ddcb9cf8c8 [misc] downgrade a warning message from clients leaving non-joined rooms 
This can now happen all the time, as we skip the join for clients that
 disconnect before joinProject/joinDoc completed.

94d57f50c0 add fake lint and format targets 
Highly hacky!
Lint and format steps are coming very soon thanks to the decaf, but in the
meantime we need steps to pass CI. Updating the build scripts after the
decaf will undo this change.

d13acb8ca3 [ChannelManager] port related and still mostly valid test from v2 
I skipped the bulk of verifyConsistentBehaviour tests which are not
 valid for the new implementation -- there is no optimization and
 always cleanup.

1095851dfe [misc] test/unit: fix typos and assertion of error messages 
Sinon does not check the contents of the passed error when checked via
 sinon.stub().calledWith.
```
callback = sinon.stub()
callback(new Error("some message"))
  .calledWith(new Error("completely different message"))
  === true
```

Cherry-pick plus an additional patch for the joinProject bail-out.

55af5e502f [WebsocketController] skip leaveProject when joinProject didn't complete 
Also drop dead code:
 - user_id bailout

   There is a check on a completed joinProject call now. It will always
    set a user_id, see Router.coffee which has a fallback `{_id:"..."}`.

 - late project_id bailout

   WebsocketLoadBalancer.emitToRoom will not work without a project_id.
   We have to bail out before the call.

cb675d38c2 [misc] SafeJsonParse: align the size limit with the frontend->rt limit 
frontend -> real-time and doc-updater -> real-time should be in sync.
Otherwise we can send a payload to doc-updater, but can not receive the
 confirmation of it -- and the client will send it again in a loop.

Also log the size of the payload.

15244a54be [misc] WebsocketController: limit the update size to 7mb 
bail out early on -- especially do not push the update into redis for
 doc-updater to discard it.

Confirm the update silently, otherwise the frontend will send it again.
Broadcast a 'otUpdateError' message and disconnect the client, like
 doc-updater would do.
