- change the interface of Storage.get_meta() and .set_meta() to use '' as the empty value and None as missing value. - When a property is missing (e.g calendar-color was removed) in the filesystem storage delete the 'color' file, and in the WebDAV storage issue propertyupdate/remove call. - remove the property from [status]/[pair]/[collection].metadata I have adjusted, but not run the test suite. On the other side I tested on real system: source is CalDAV - destination is filesystem; and source is CalDAV, destination is CalDAV (another account)
