[FIX] crm: lost button don't trigger lost reason popup in list for leads

Steps to reproduce:

- Install crm
- Go to settings and activate leads in crm.
- Go to leads list and select any lead, now mark it as lost.

Issue:

It will ask for lost reason. But if we do it from the Leads form view,
we don't get to set any reason. I discussed with the PO and we don't
want to add the lost reason in the leads.

Solution:

Modified action of lost so it takes leads into account.
