Closes https://github.com/sourcegraph/sourcegraph/issues/33813

Note: This is a temporary hot fix. Caching is basically broken here. We should come back to this issue in the future to fix the caching.

Go to any filterable insight. ex: Using regex Open the filter panel Filter for any repo that doesn't exist. i.e. "hash" Click the reset button Graph should reset back to previous values
