Birthday format error

[tcorbly]

Entering a birthday with dashes instead of slashes causes the birthday to be stored incorrectly. This also causes user to be marked as someone needing a parent or guardian email despite being over age.

Example Input: 01-01-2002
Example Stored Value: undefined-01-01-2002-undefined
Example Parent Approval Form: 01/01/undefined

@tcorbly this should've been fixed by #506.

Can you see if it's still happening in prerelease? If not, then a release of v2.0.2 should fix it for everyone
