[FIX] mrp: Manufacturing routes all get reference 'New'

When creating a manufacturing route in 2 companies in a multi-company environment,
only the routing 's reference of 'My company' got a sequence but the routing 's reference
of the other company stayed 'New'. Now the default sequences for mrp.routing are shared
between companies like SO and PO.
