don't kick client for invalid message (#1673)

## Description:

There is a race condition causing clients to send intents before
joining:

1. User requests to join a Game
2. The Worker does authentication & authorization
3. User requests to send an intent before joining the game, so the
request is sent to the worker

So instead of kicking the client, just log a warning and drop the
message.

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced
- [x] I have read and accepted the CLA agreement (only required once).

## Please put your Discord username so you can be contacted if a bug or
regression is found:
