LP#1828114 Incorrect date of birth saved in certain time zones

The Angular and AngularJS patron edit/register interfaces save
the birth date one day before the selected date if the client
device is set to a UTC+ time zone.

This patch converts the Date object to a formatted date string
without converting it to UTC.

To test:
1. Set your device time zone to a time zone after UTC
2. Edit a patron's date of birth in the AngularJS interface
3. Note the saved date of birth is 1 day earlier than expected
4. Repeat steps 2-3 for the Angular interface
5. Apply patch
6. Repeat steps 2 for both the Angular and AngularJS interfaces
7. Note the saved date of birth is as expected
