partner_multi_company breaks contact widget

[dynapps]

Module

partner_multi_company

Describe the bug

After partner_multi_company is installed, the display name is stored
As this is stored without the extra context parameters, the address, email, vat, ... are not included
thus when the contact widget is used, it only shows the name

To Reproduce

Affected versions:
tested on v17.0 of runboat

Steps to reproduce the behavior:

1. After the module is installed, open any form or report where the contact widget is used, and you will see that only the address is name is displayed
   example: on invoices the context uses show_addres: 1, but only the name is displayed

Expected behavior
contact widget should continue to work after installation of this module

I also tested on v16 of runboat, and there it works as expected

After looking into this further, it seems version 17 uses a stored complete_name and does not store display name any longer
so maybe storing display name in this module is no longer needed
