Alex Vanin fae03c2b50 [#78] Process 'not found' error when object exists in tree
When object exists in tree but missing in storage, we can't remove
bucket. While storage node does not sync tree service and object
service, the only way to delete such broken bucket is to ignore
'object not found' error, clear cache and do not include missing
objects in the listing result.
