[FIX] industry_fsm_sale: unlink SO when no SO item is linked to a task

Enterprisesaas-18.2sale_projectindustry_fsm_saleMedium

This update resolves an issue where tasks remained linked to sales orders even without associated order items, hindering billing processes. The change ensures tasks can be properly detached from sales orders when no items are linked, streamlining billing and allowing for easier task management. This improves the flexibility of using tasks for non-billable services.

Original PR description

Currently, a task remains linked to its original sales order even when it has no sales order item. This prevents users to not bill a task and temporarily detach it from a sales order until it can be linked to a new one.

**Steps to produce:**
* Install Sales, Project
* Products > Virtual Home Staging > Create On Order > Project and Task
* Create and confirm quotation with that product.
* Tasks > Empty Sale Order Item Field

**Observed Behavior:**
* Sale Order is still linked to the task despite sale order line has been unlinked from that task.

**Root cause:**
* Compute method [1] only detaches the sale order if the customer has been changed.

**Solution:**
* Only detach the sale order when there are no sale order items and the record is not a field service task.
* Field service tasks should always keep the sale order linked so materials can still be added to the existing sale order, even when the task is non-billable (i.e., no sale order line is linked). This logic is handled by the compute override at [2], which reassigns the sale order when needed.
