test: add url type check in Module options

Hi. this is my first time contributing to an open source project. I'm a newbie here. From the Node.js Nightly Code Coverage, I noticed that the code coverage in root/internal/vm/Module.js lacked some test coverage for the url options parameter. The test just adds a check to ensure an error is thrown.

The change is a relatively small one. I took a look at the other lack of test areas for that file, but perhaps I'm not familiar with the codebase to know how to test those.

Any help would be appreciated.
