tests got skipped on OC storage driver because they seem to fail randomly, ticket to track the issue: owncloud/ocis#637

[phil-davis]

Do we also need to test this for shares?
When the sharee changes something in a share, then etag of the parent... folders changes for both the sharer and sharee.
And for the sharer changing something - the sharee sees etag changes (so that a client sync app run by the sharee will notice a change...)

Update: the issue owncloud/product#144 has items listed for testing shares, so that will be covered in future PRs.

yes we also need sharing tests, will do them in a new PR
