improve friend.find_presence_model_for_uri_or_tel, fix core.interpretUrl to normalize both phones and usernames

That commit doesn't fix anything but it is a better way to have
LinphoneFriendList objects created with a refcount to 1 systematically.

make sure normalized phone numbers are computed for each new subscription to take into account potentiel proxy config changes.

fix test (adjust waits to take into account that dialog expiration doesn't trigger a new refresh (we let the SUBSCRIBE transaction timeout to trigger a new one instead).
