vote: Reset the truth counter to 1 if the key changes

In order to fill the missing truths with 0, a counter follows the next expected
truth number.
If it suddenly drops down, we changed player and it should reset as well.

However, as not all players are voted for on all truths, we might change players
but get a higher truth, which was not taken into account and could miss all
the zeroes at the beggining for this player.

Reset the counter if we change players.
