add bloom filter false ratio tests
Patch by Jaroslaw Grabowski, reviewed by brandonwilliams and paulo for
CASSANDRA-15834
Verifies if BloomFilterFalseRatio takes into account true negatives.
Without this fix, the following scenario (many reads for non-existing
rows) would yield BloomFilterFalseRatio=1.0. With the fix we assume
it should be less then the default bloom_filter_fp_chance.
