Polish call blocking rotation/undo behaviors.

+ Correctly dismiss filtered number dialog on rotate.
+ Polish listener interface, and extend across all block/unblock
and undo scenarios.
+ Update UI across all blocking scenarios (call log, call detail,
settings, blocked number list, blocked number search);
+ Conslidate creation of FilterNumberDialogFragment in a single
static method.

The listener interface is not ideal, because it does not maintain
state well across rotation and multiple instances. This option was
selected, however, because of the number of scenarios in which
the dialog is invoked and various circumstances (in a RecyclerView
list item, in a fragment, in an activity). This range of scenarios
makes it convoluted to implement a uniform mechanism in any other
way, so the approach opted for is to set a listener, and dismiss
the dialog on rotation..
