Fix problems with javascript e2e tests

[aehnh]

• email OTP fails, only with cloud staging backend (with local backend it works)
  • javascript code reverted to before the web-js related commit, the problem still persists
  • local playground + local backend = passes; local playground + cloud staging backend = fails; vercel playground + cloud staging backend = fails
  • to reproduce the bug manually, try email OTP on a project shortly after it has been created by a test run. however, after ~2 minutes of waiting (after the test ends), email OTP works fine again on that project
• after test cleanup deletes the projects, they are deleted from devpanel, but they persist in the database as active
  • this behavior is consistent across local and cloud staging backend deployments, so I suspect this is not related to the first bug

It resolved itself after several days but it might occur again because we never found the cause
