fix: add a missing await in tests/integration/common

[fastfadingviolets]

Summary

Calls to testDb.create have to be awaited even if they go through a catch. This was a race condition that could be triggered on slower machines, etc.

Checklist

• On the frontend, I've made my strings translate-able.
• If I've added shared components, I've added a storybook story.
• I've made pages responsive and look good on mobile.
• If I've added new Firestore queries, I've added any new required indexes to firestore.indexes.json (Please do not only create indexes through the Firebase Web UI, even though the error messages may reccommend it - indexes created this way may be obliterated by subsequent deploys)

Screenshots

Add some screenshots highlighting your changes.

Known issues

Steps to test/reproduce

For each feature or bug fix, create a step by step list for how a reviewer can test it out. E.g.:

1. Go to the home page
2. Click on a testimony
3. See that it's loaded with a loading spinner
