Enable parsing phone number in ContactLoader

A new flag has been added to the ContactLoader to compute
a formatted number based on the original phone number,
phone number in E164 format, and the default country code
iso. Only the ContactLoader for the contact detail card has
been enabled to compute this formatted number.
