Show dialog if multiple candidates exist

In GB we show a list of phone number to call in Favorites
screen, while we don't now.

Also refrain PhoneNumberInteraction from showing a dialog
by itself but let a nested class do instead. showDialog() is now
obsolete and we should use DialogFragment instead.
