Game init errors must ends the game, not freeze it

Use case:
* Run server in [test mode](https://github.com/magefree/mage/wiki/Development-Testing-Tools#server-test-mode) (e.g. without deck validation);
* Start Tiny Leaders game with auto-generated deck (in normal situation commander/leader name must be in deck name);
* Game started, you will see empty battlefield, but no player selecting -- it's a game freeze. Error log goes to `magediag.log`;

Game must ends normally after fail on starting/init.
