Fix crash on e2e test failure

[Gudahtt]

If an e2e test fails on a website, the driver will crash on this line because it can't find a reference to stateHooks. That variable is only set in our UI, not on other sites.

Manual Testing Steps

Not sure this needs manual testing. An example of the crash is here though: https://app.circleci.com/pipelines/github/MetaMask/metamask-extension/30900/workflows/90e1609a-a961-438b-b328-651eb2e0e00c/jobs/806238

Pre-merge author checklist

• I've clearly explained:
  • What problem this PR is solving
  • How this problem was solved
  • How reviewers can test my changes
• Sufficient automated test coverage has been added

Pre-merge reviewer checklist

• Manual testing (e.g. pull and build branch, run in browser, test code being changed)
• PR is linked to the appropriate GitHub issue
• IF this PR fixes a bug in the release milestone, add this PR to the release milestone

If further QA is required (e.g. new feature, complex testing steps, large refactor), add the Extension QA Board label.

In this case, a QA Engineer approval will be be required.
