TUIO: Confirm with wrong player causes current state to be lost

[ukch]

To reproduce:

• Start TUIO and the game. Move fiducial 2 onto the game board so that the shape outline appears.
• Put fiducial 201 (black confirm) onto the board. Nothing appears to happen, but a warning is logged in the terminal: 'Caught unauthorised confirm for player 2'
• Put fiducial 101 (white confirm) onto the board.

Expected behaviour:

1. The shape should be confirmed
2. Evolution happens
3. The next player's turn begins

Actual behaviour:

• The shape is lost. The next player's turn begins as expected, meaning the white player has essentially wasted their turn.
