To remove the application completely firstly remove the admin_view_permission from your INSTALLED_APPS setting and then open a debug shell and execute the following commands in order to remove these extra permissions from the database:

from django.contrib.auth.models import Permission
permissions = Permission.objects.filter(codename__startswith='view')

Notice: Before delete the permission would be helpful to check if the permissions queryset contains only the view permissions and not anything else.
