When creating ticket, add item without the need to push the "Add" button

Original GitHub issue:

https://github.com/glpi-project/glpi/issues/17909

1. Press "Create a ticket"
2. Go to "items" section
3. Choose an item
4. Notice that if you don't press "add" right below the items, but use the "+Add" button at the bottom of the page, ticket gets created without the asset assigned to the ticket

It would be great if item would be added to ticket without the need to push the "Add" button.
