500 error when submitting Pre-Reg form with default "Age" field

Submitted valid pre-reg form without populating the "Where Do You Want To Help" section and left "Age" value as "Click To Select". Received the following error:

May also be due to leaving "Age As Of Anthrocon" as "Click To Select".

Whoops! model_checks.py has a way to catch an invalid birthdate, but I accidentally added this line before that check. It's easy to fix, at least.

Fixed in ac-staging.
