Remove fuzzy finder cache storage.
Created by: olafurpg
Previously, it was slow to download files in larger repositories so the fuzzy finder used the cache storage to speed up subsequent loads. This commit removes that caching because
- downloading files has gotten faster https://github.com/sourcegraph/sourcegraph/pull/21422
- filenames are already cached by the SPA as the user navigates between
files. Files only need to be re-downloaded when refreshing the
browser. The original implementation used raw
<a href=
links, which trigger a cold refresh.
