Random player card appears

[addonovan]

The dealer's second card (?) might display under the first player's text field instead of the dealer's position.

Steps to reproduce:

1. Start the game
2. Start the dealer program
3. Let the game run on auto
4. On the last turn, the dealer's second card may appear in the first player slot

This may not be a problem on our end, actually. Or, if it is one, is just due to the UID being too long (which does need to be fixed!). Below, you can see some logging possible since debugging changes were made in #42.

The game is receiving multiple sets of cards belonging to a player with the same UUID, which shouldn't be possible. Because of how m_player_index is saved, the first set is displayed as "ours" and the second is displayed as the first other player at the table.
