Fixed that Call back function didn't work

Call back function on missed call notification didn't work after
switching user from gust to owner. Because UserHandle was saved in
extra when creating the pending intent and it was previous one after
switching user to owner. Fixed to use FLAG_CANCEL_CURRENT.
