Purpose/Overview:
In order to support UIIN-574 - In the Acquisition accordion for the holding need to show order details information

Requirements/Scope:

Prevent creation order line where Location element contains both "locationId" and "holdingId".

One of  "locationId" and "holdingId" should be in Location element

Use Cases:

1. Location of the POL should contain reference only on holding (holdingId)   

Given “Create inventory” for physical or electronic have “INSTANCE_HOLDING”  OR "INSTANCE_HOLDING_ITEM"

2. Use method from (1) in the :

• org.folio.helper.PurchaseOrderLineHelper#createPoLine(org.folio.rest.jaxrs.model.CompositePoLine)
• org.folio.helper.PurchaseOrderLineHelper#updateOrderLine(org.folio.rest.jaxrs.model.CompositePoLine)

Acceptance criteria:

• Logic updated
• Unit tests
• API Tests updated or created
