Merge branch 'dev' into swiftyos/caching-pt2

When a graph is not found/accessible, we now clear the cache entry rather than
caching the None result. This prevents issues with store listing permissions
where a graph becomes accessible after approval but the cache still returns
the old 'not found' result.
