If a values associated type `Serializable` , equals the values type, `toValue` would infinitely call itself. The test `testWrongCast` reproduces this and I fixed it by comparing the `nextType` with the current type.

Same as the above comment, and please use XCTAssertFalse instead of XCTAssertEqual as linter suggests.

I initially used that, but since get returns on optional, I'd have to provide a default value. That feels less clean.
