Title: Use ancestors' `hash_including` if available.

The previous solution didn't work because rspec does a complicated dance
with module inclusion and inheritence, so we must check this condition
at call-time, rather than include-time.

@bblimke sorry about this, we had not tested this thoroughly enough the first time. Hopefully nobody has been bitten yet. cc @strongriley
