Fix pp when passed a empty ruby2_keywords-flagged hash as array element
This causes problems because the hash is passed to a block not
accepting keywords. Because the hash is empty and keyword flagged,
it is removed before calling the block. This doesn't cause an
ArgumentError because it is a block and not a lambda. Just like
any other block not passed required arguments, arguments not
passed are set to nil.
Issues like this are a strong reason not to have ruby2_keywords
by default.
