Currently the URL API is only used from the JS binding, which always initializes `base` regardless of `has_base`. Therefore, there is no actual security risk right now, but would be had we made other C++ parts of Node.js use this API. Refs: nodejs#14369 (comment)

Currently the URL API is only used from the JS binding, which always initializes
baseregardless ofhas_base. Therefore, there is no actual security risk right now, but there would be had we made other C++ parts of Node.js use this API.Because of that, I was not able to add any JS tests, instead resorting to C++. However, the magic of C++ compilers makes a reliable test impossible, as the added test only sometimes fails before this PR, even though when it does fail it is a NULL pointer dereference.
