test: improve users edit tests

- Rename test for friendly forwarding to be more concise
- Add a separate test for successful user edit

These changes enhance the clarity of the test suite by
providing a more descriptive name for the friendly forwarding
test and separating the successful edit functionality into
its own test case, improving maintainability and readability.
