When creating a new company from a move, if the tax ID is repeated, a warning is displayed.
The warning includes the company name, address and VAT, if those have been added. In this case,
address is shown in an extra line, which looks broken.
This commit removes additional partner information by updating the context,
displaying only the partner name.
It also slightly rewords the warning, from "are you sure to create a new one?" to
"are you sure you want to create a new one?".
To replicate the issue:
1. Create an invoice
2. Click on the empty field next to Customer, type a new name and click "Create and edit..."
3. Add a Tax ID that is already in use (e.g. US12345673)
4. Warning of duplicate Tax ID shows, displaying company name, address and VAT
