Bug 29213: Fix typo ol in member-alt-contact-style.inc

There is a typo in member-alt-contact-style.inc, tag ol is open twice for alternate contact.

Test plan :
1) Create new patron
2) Look at HTML structure in "Alternate contact" section
=> Without patch you see <ol> twice and </ol> once
=> With patch you see once <ol> and </ol>
