Test that a tab that should be displayed is displayed

On the CI project, the "Invoice Data" tab should be displayed for invoice document tab. It displays dublincore layout as well as lifecycle state.(which is customized).

Checks that should be ran:

• Invoice Data tab is displayed on a just-created Invoice.
• Invoice Data tab is not displayed on a File document
• On the Invoice Data tab, we can find the lifecycle init state : "received"
• On the Invoice Data tab, we can find the "amount" value that was given when creating the invoice. (because it displays a layout created in studio and displayed using a layout defined on the layout feature )
