Change subject: Avoid key fragmentation in FileBackend
......................................................................
Avoid key fragmentation in FileBackend
* Make sure that global backends do not prefix the cache keys
with local wiki IDs for container and file stat entries.
This causes fragmentation and breaks invalidation.
