test: fix failing CI test and improve test assertions in requestErrorConfig

- Fix 'should append token to URL' test that expected non-existent token
  attachment logic (source code has it commented out); now tests actual
  pass-through behavior
- Add expect.assertions(5) to try/catch BizError test to prevent false
  positive if errorThrower doesn't throw
- Move navigator.onLine restoration into finally block to prevent state
  leak on assertion failure
- Replace tautological REDIRECT assertion with meaningful verification
  that no message/notification is triggered
