test(permissions): remove OpenScreenRecordingSettings test that pops System Settings UI

The test called open x-apple.systempreferences:... on every unit test run,
opening System Settings on the developer's machine. The assertion was also
trivially meaningless (asserting err is of type *error, always true).
Removed; behavior is covered by VM-level tests in a controlled environment.
