swkbd: Fix a bug where clicking Cancel hangs the game (#5294)
* swkbd: Fix a bug where clicking Cancel hangs the game

The text is validated in `Finalize`. If the validation fails, an error is returned and the applet is not actually finalized. This can result in hangs.

This is usually not a problem as the frontend is expected to validate the text passed to `Finalize`. However, when the user clicked on `Cancel`, the text is ignored and the frontend won't do any validation. Therefore, we should skip the validation here as well.

Also fixed a potential data race. All these functions should now be called on the same thread
