USE_THOUSANDS_SEPARATOR = True, causes foreignkey id to become localized

[George Tantiras]

After upgrading to Django 1.11, when a foreignkey points to an id with more than 3 digits, it gets localized.

In django admin, when I visit an already existing instance and hit "Save and Continue Editing", I receive the following error:

Exception raised while rendering {% include %} for template 'admin/change_form.html'. Empty string rendered instead.

Changing the setting:

USE_THOUSANDS_SEPARATOR = False

renders everything back to normal.
