Auto merge of #14493 - fokinv:stopnotifications, r=jdm

Fixed some typos in stopNotifications test.

<!-- Please describe your changes on the following line: -->
We called the startNotifications() method instead of stopNotifications() in the tests. According to the specification this method should return `InvalidStateError` and not `NetworkError`, so we changed that as well.

<!-- Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `__` with appropriate data: -->
- [x] `./mach build -d` does not report any errors
- [x] `./mach test-tidy` does not report any errors

<!-- Either: -->
- [x] There are tests for these changes

<!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. -->

<!-- Reviewable:start -->
