[FIX] crm: changing salesteam field in mobile without error

Steps to reproduce:
- Install CRM module and go to any lead view.
- Make sure we are in mobile mode, and the page was loaded in mobile
mode.
- Go to Extra Information, and try to change the sales team field.

Issue:
We got an error since we didn't have a proper view for this field in
mobile.

Solution:
Adding the proper `kanban_view_ref` as in similar fields will fix the
issue and let us change the field without error.
