    neutron: Unbind remaining ports after PortNotFound

    Just because we encountered a PortNotFound error when unbinding a port
    doesn't mean we should stop unbinding the remaining ports. If this error
    is encountered, simply continue with the other ports.

    While we're here, we clean up some other tests related to '_unbind_port'
    since they're clearly duplicates.
