Fix issue with entry of multiple assets via Lots entry modal

[jmcameron]

When you enter lots (by integration) and you want to add multiple instances of an asset, this PR makes this work more easily from the Lots modal popup.

Closes #6709

TESTING

• use bhima_test
• Go to: Stock > Stock Entry
  • Select [Integration]
  • Add a new line for an asset. Use inventory code: MOT.HCRF250RX for a motorcycle
  • Click on the Lots link to bring up the Lots entry modal.
  • You should now be able to change the global quantities
  • Since Assets must be unique with quantity===1, the quantity field is not even shown
  • Try added multiple lines (with different LOT ids)
  • Click [Submit] on the modal
  • Try clicking the Lots link again to verify that the info on the non-yet-saved lots is still there
  • Close the modal
  • Try adding a non-asset (eg, inventory code DINJ_TRIB1A2_0) and use the "Lots* link and verify that the Lots modal works as normal for non-assets
  • Close the Lots entry modal
  • Click on the [Submit] button to enter the stock.
  • Check the receipt document to verify correct enty
• Go to Asset Management > Assets Registry and verify that the new assets appear there.

I do not think it is related to this PR, but I have noticed that the quantity is doubled in the receiver depot when we do the entry with this link in the "Expedition Registry":

In the case below I have just received 3 Vehicule but it shows 6 instead.

We can see the quantity doubled in the "Lot Registry"

To reproduce that:

• yarn build:db
• Do a stock entry operation in a the Depot Principal of 3 Assets (MOT.HCRF250RX)
• Do a stock exit operation to the Secondary Depot of 3 Assets
• Do the stock entry operation in the Secondary Depot by using the link in the "Expedition Registry"
• Consult the "Articles en stock" and "Lot en stock" registry to check quantities

Here is another observation for a "Stock Entry" by using the "Transfert" button in the "Stock Entry" module, when we select the shipment the grid is filled with the doubled quantity:
