Make FloatingActionButtonController view visible.

Make FloatingActionButtonController visible when back button
is pressed at dialchooser view, and again on clicking add call
option. Because if back button is pressed at dial chooser list,
and again it is launched, then FloatingActionButton is not
turning visible.
