[IMP] crm, hr_recruitment: add default model when creating activity types

Purpose is to help managers in their daily use of activities. When creating
a new activity type through an app-dedicated menu we should pre-fill the
model with the main app model. This is already done in several applications.
This commit fixes some applications where it was not done.
