Ensure that is_primary is set to TRUE whenever we create a phone, email, IM, openID record IF it is the only record for that contact

Currently you can insert a phone record (for example) via API (and I think also via Profile) - and the is_primary flag is set to 0 even though it's the only phone record for that contact. This causes problems in the EDIT Contact UI (as well as other interfaces). We should ensure that is_primary is always set TRUE for all these objects if they are the only one for a contact.

EXAMPLE: Using the location_create API insert a phone number for a contact that does not yet have a phone record...

require_once 'api/v2/Location.php';

$workPhone =array('phone' => '02327276048',
'phone_type' => 'Phone');

$phones = array ($workPhone);

$workEmailFirst = array('email' => 'xyz@indiatimes.com');

$workEmailSecond = array('email' => 'abcdef@hotmail.com');

$emails = array($workEmailFirst,$workEmailSecond);

$params = array(
'phone' => $phones,
'city' => 'Mumbai',
'email' => $emails,
'contact_id' => $contactID,
'location_type_id' => 3
);

$locationAdd =& civicrm_location_add( $params );
