When Odoo display a phone number number, on phone or if VOIP is
installed a invisible `­` character was added from 9.0 up to
saas-11.2 so an applications such as skype would not be concerned with
the number.
But if someone copy-pasted from this to somewhere else in Odoo, we would
get incorrect number with this invisible caracter. So this change make a
special case for the "FieldPhone" so the character is removed from data
saved.
