Title: Bug 827753 - [DIALER] When using the keypad during a call to a contact with a long name, name shown changes (r=fcampo).

According to UX guidelines, the font sizes of the phone number or contact name have been adjusted. In case that during a call, the keypad is expanded, tones sent and the keypad is hidden, the font size is also restored.
