Updating AsyncQueryHandler with FilteredNumCompat

+ FilteredNumberAsyncQueryHandler needs to make use of the
FilteredNumberCompat class to unsure that it is

enabled.

+ This CL updates the queryHandler to the FilteredNumberCompat class
for the hasBlockedNumbers, isBlockedNumber, and blockNumber
operations.
