Merge lp:~dawgfoto/duplicity/skip_sync_collection_status into lp:~duplicity-team/duplicity/0.7-series

[Martin Nowak]

collection-status should not sync metadata
- up-to-date local metadata is not needed as collection-status is generated from remote file list
- syncing metadata might require to download several GBs

The syncing was introduced with http://bazaar.launchpad.net/~duplicity-team/duplicity/0.7-series/revision/759.2.1/duplicity-bin but seems unnecessary/unrelated to fix that bug.
