Disable vote abandon when the party is not full

[umbralcadenza]

PSA: If you leave a party during a Duty when it is not full, you incur no penalty for abandoning the group.

That said, there is 0 reason to have Vote Abandon available when the party is not full, and having it inadvertently griefs players who don't want to leave. If you have two people who are too impatient to, say, wait for another tank to happen and one who doesn't want to sit in another 20 minute queue again, the two people who want to leave--because they don't understand how the system works--will attempt to Vote Abandon, they'll both say yes, and the person who doesn't want to leave gets forced out for no reason.

Please address this. Players shouldn't be able to waste your time in such a senseless and flagrant fashion.
