the rma module had company_id fields on rma.order and rma.order.line but not on rma.operation,
and no global multicompany record rules.
-> we fix this and avoid a mess with people allowed to see an operation in the drop down list
but unable to use it because if points to a warehouse of another company
[IMP]Separate menus for customer and supplier operations
* Add active field to rma operation
* Added tests
* Fix travis
* Fix create supplier rma from customer rma
