Incorrect defaults loaded when two phone fields are added to the same profile one primary and one not primary (EG. Home) with different phone types

Originally commented on in CRM-14470 which was also about when there are 2 primary fields.

See also related issue CRM-13011. (See comment around line 938 about CRM-13011)

To replicate:
Create a profile with the following fields:

• first name
• last name
• phone type = mobile, location type = primary
  (location type will become work using default settings)
• phone type = phone, location type = home

create a contact with the profile
edit the contact and set the home phone to be primary
reload the profile in edit mode
The home phone will be shown in both the home and mobile fields.
