Since 7.1, we have been storing entries when they are associated to default display pages and not storing them when we don't want to have a display page for entries.

The idea of the task is to interchange this logic, basically:

Entries linked to the default display page template are not stored in DB.
Entries that don't have a display page template are stored in the DB.
