treewide: Remove getUri and replace with getHumanReadableURI where appropriate

Browse source 
The problem with old code was that it used getUri for both the `diskCache`
as well as logging. This is really bad because it mixes the textual human
readable representation with the caching.

Also using getUri for the cache key is really problematic for the S3 store,
since it doesn't include the `endpoint` in the cache key, so it's totally broken.

This starts separating the logging / cache concerns by introducing a
`getHumanReadableURI` that should only be used for logging. The caching
logic now instead uses `getReference().render(/*withParams=*/false)` exclusively.
This would need to be fixed in follow-ups, because that's really fragile and
broken for some store types (but it was already broken before).
