Adding required fields on company model is annoying for tests. Indeed multi company tests may run during module installation, notably in CRM. Those tests generally require to create a new company which is not possible if the column is required but module not already loaded in registry. This is the case if for example hr_expense is installed and updating CRM. When possible, avoid required fields on a such used model as company. In this case we can easily consider a void value as 'no_send'. In this commit we simply make the field not required in database but set a required on the view itself to avoid confusion. That way behavior is still the same, existing databases are left untouched as all keys still exist and running tests is smoother.
