Test failures.

[bangpound]

When I run the tests in this project with PHP 7.1, I get two failures. The actual results from the Jenkins hash function don't match what is expected.

There were 2 failures:

1) RocketLabs\BloomFilter\Test\Hash\BloomFilterTest::addBulkFilter
Expectation failed for method name is equal to <string:setBulk> when invoked 1 time(s)
Parameter 0 for invocation RocketLabs\BloomFilter\Persist\Persister::setBulk(Array (...)) does not match expected value.
Failed asserting that two arrays are equal.

FAILURES!
Tests: 29, Assertions: 42, Failures: 2.

Are the test expectations wrong? If so, I can open a PR to address it.

OOI, does it break on older PHP versions?
