Bug 27717: Display date of birth even if the patron is under 1

This patch moves the 'age' condition to below the date of birth display,
allowing the date to display for babies.

Test plan
1/ Add a user with a date of birth within the last year
2/ Check that the date of birth appears on the patron details page
(under contact details) with the patch applied.
