Description
When using django-cms together with versioning it's important to keep apart content/objects that should be displayed to the end user and content/objects that can be viewed by an admin user.
get_title_obj is used in several places to assign the object both in toolbars (admin related) and in places that will render to the end user.
There has been a lot of monkeypatching going on in djangocms-versioning to account for this fact. By creating a method get_admin_title_obj this method alone could be monkeypatched instead of spreading out the monkeypatching. If/when versioning is incorporated into core it would also make things easier to incorporate any monkeypatches into this method.
This will also start to setup us up for a clean separation between what is viewable by admin users and what is viewable by end users.
This is also related to the following PR > django-cms/django-cms#6817 instead of that implementation it would be better if it used get_admin_title_obj
