Add reset for birth_date.

[puresyntax71]

Overview

When "Fields to Lock" is enabled and birth date for contact is also enabled, clearing of fields doesn't work for birth date form control which makes the field not show up.

Before

Hiding and clearing of existing contact field doesn't make the birth date field re-appear.

After

Birth date field shows up again.

Attached is an example yaml:
