Fixes gh-160761

When URL result objects (SplitResult, ParseResult, DefragResult, etc.) are instantiated directly rather than returned from urlsplit() or urlparse(), their _keep_empty attribute is not set.

In this case, super().__getstate__() returns None. _ResultBase.__getstate__() attempted to subscript state[1], causing TypeError: 'NoneType' object is not subscriptable.

This change checks if state is not None before accessing state[1], and adds tests verifying that all result types can be pickled when created directly.

Thanks for the review, @picnixz!

I've addressed the feedback:

Applied if state is None: return None in urllib.parse to keep the diff minimal and the check explicit.
Removed the extra blank line in test_urlparse.py.

Please take another look when you get a chance!
