Before we have only owner_id to determine group owner
With multiple owners per group we should get rid of owner_id in group.
So from now @group.owner will always be nil but
@group.owners return an actual array of users who can admin this group

This also makes that 'mv: cannot stat `/ho..' is not shown in the test :)
