igbinary_unserialize should never convert from packed array to hash when references exist (Bug #48)

	// The default hash size is 16. If we start with 0, and aren't careful, the array would begin as a packed array,
	// and the references would be invalidated when key 50 (>= 16) is added (converted to a hash), causing a segfault.
