Before this change the VFS cache could get into a state where when an
object was updated remotely, the fingerprint of the item was correct
for the new object but the data in the VFS cache was for the old
object.
This fixes the problem by updating the fingerprint of the item at the
point we remove the stale data. The empty cache item now represents
the new item even though it has no data in.
This stops the fallback code for an empty fingerprint running (used
when we are writing items to the cache instead of reading them) which
was causing the problem.
Fixes#6053

Before this change, if we restarted an upload after a restart then the
file would get uploaded but never added to the directory listings.
This change makes sure we add virtual items to the directory cache
when reloading the cache so that they show up properly.
