Adding "ABSENTNUMBER" to the list of known constants from network.

CDMA networks can sometimes send "ABSENT NUMBER" or "ABSENTNUMBER" as
the return number for incoming calls.  This gets converted to a better,
localized string within Phone.

Previously we were only recognizing the format with space.  This CL adds
"ABSENTNUMBER" to that list.
