Another strange behavior.
I was't able to remove the old OVN provider since a few logical networks
was still attached to that.
So I removed all of them from the engine and then I manually removed the
old OVN provider and only at this point all of my old logical networks
manually reappeared in the engine as attached to the new 4.2
'ovirt-provider-ovn'.
