tdf#105844 package: ODF wholesome encryption: use package version
... to init the Version property. The problem is that the outer storage loaded from a wholesome ODF encrypted document doesn't have a Version, because it doesn't (directly) contain a document and has no "/" file-entry. Extract the root element's package version attribute and use it. The Storage API doesn't distinguish much between the package version and the root document's (i.e. root folder's) version.
