Diff Editor no longer works with version 2.10.0

[ILZ1105]

Describe the bug

To Reproduce

1. Upgrade from 2.8.0 to 2.10.0
2. Try upgrading any deployed application within kubeapps and the check the diff editor (you can even use kubeapps itself)
3. No green/red lines will show up anymore

Expected behavior
Diff editor still shows the red/green lines for comparison.

Screenshots
None

Desktop (please complete the following information):

• Kubeapps Version 2.10.0

Thanks for reporting it; it is odd since we have some automatic e2e tests checking the diff view, but we will look into it soon.

It's odd indeed, I was checking through the logs to find any kind of error but it's a bit tricky as I have numerous issues at once with 2.10.0 that I'm still looking into. One of the bigger issues seems to relate to postgresql #7702 which caused quite a bunch of problems with synching the repos. I even had to manually delete the entry in the DB of the synched repo (the hash value) to be able to sync bitnami again. I rolled back to 2.8.0 and upgraded to 2.10.0 again and it was fine this time, though the DB was still overloaded because I couldn't increase the CPU for it as described in the bug.

There might be a chance it's related to that?
