commit 6890933e4af9d0e7919b3b7fc30e184e2196dbe7
Author: Morris Jobke <hey at morrisjobke.de>
Date:   Thu Dec 10 11:21:28 2015 +0100

    Deduplicate version expire jobs
    
    * versionSize is calculated anyway in the expire job - > dropped
    * offset/neededSpace was needed for expiry before the file is moved to the versions -> now this is included already in the currently used space because the expiry job is defered to a point in time after the version creation
    * fixes #21108
