Update error load fail test so that webdriver can still connect to app

[ijjk]

This attempts to address this test failing intermittently with the below error by not closing the next server before the test has finished and instead removing the client _error.js bundle so it still 404s but doesn't cause webdriver to be unable to connect to the next server

 WebDriverError: unknown error: unhandled inspector error: {"code":-32000,"message":"Inspected target navigated or closed"}
      (Session info: headless chrome=80.0.3987.106)

      27 |     await check(async () => {
    > 28 |       return !(await browser.eval('window.beforeNavigate'))
         |                ^
      29 |         ? 'reloaded'
      30 |         : 'fail'
      31 |     }, /reloaded/)
