push change to MR branch -> go from Overview to Changes tab on MR page -> error alert
If you push changes to the branch for an MR and then in the browser switch from the Overview to the Changes tab for that MR without reloading the page first, you get an error alert at the top of the Changes tab.
To reproduce:
1. Create an MR
2. Open the MR's Overview page in the browser
3. Make changes to the MR branch locally and push your changes
4. After git push successfully finishes on your local, go to the browser and click the "Changes" tab.
Expected: Go to the changes tab. The changes you just pushed are visible.
Actual: Go to the changes tab. The changes you just pushed are visible. There's also an error alert at the top of the page saying `Something went wrong fetching the scanner findings. Please try again.`.
