Fix link not leading to Change Request

[emyller]

How are you running Flagsmith

• Self Hosted with Docker
• Self Hosted with Kubernetes
• SaaS at flagsmith.com
• Some other way (add details in description below)

Describe the bug

Clicking the "here" link on a feature flag with a pending Change Request does not lead to the Change Request. Instead, the app goes back to the feature list. There is an error in the JavaScript console (attached screenshot).

Steps To Reproduce

1. Go to the Dashboard.
2. Pick any feature flag.
3. Create a CR and leave it pending approval / publishing.
4. Go back to the feature flag. There should be a notice "You have open change requests..." — see above screenshot.
5. Click "here".

Expected behavior

The app should take me to the open Change Request.
