[16.0][IMP] purchase_requisition_tier_validation: avoid error editing alternative

[augusto-weiss]

Before this commit:

• Install purchase_requisition and purchase_tier_validation
• Create a Tier Validation for purchase model
• Create an order and an alternative
• Request for validation for one of the purchase order
• Try to edit (and save) the alternative order
• You will get a ValidationError: "The operation is under validation."

After this commit:

• You could edit the alternative (that is not under validation) without problem

@leemannd @cyrilmanuel @dzungtran89 Hi everyone! Could you see the issue?

[dzungtran89]

Hello, ok for me for the fix. Btw I think it should be an improvement rather than a fix, because you would like to except the validation for the PO's alternatives
