Broken translation status if only minor public versions exist

[timobrembeck]

Describe the Bug

When a POI or Event is published as minor edit, the translation status shows "Fallback translation", which does not make sense.

Steps to Reproduce

1. Create POI as draft
2. Do not change content and publish - this should create a new versions which is marked as minor edit
3. See translation status in language tab - it is marked as fallback translation

Expected Behavior

The translation should be up to date.
We can achieve this by setting all past versions to public, similar to how we do it for pages:

integreat-cms/integreat_cms/cms/views/pages/page_form_view.py

Lines 342 to 350 in f90e5aa

	# When a version is published and a minor edit, also publish the past versions
	# (to make sure the translation state is updated correctly)
	if (
	page_translation_form.instance.status == status.PUBLIC
	and page_translation_form.instance.minor_edit
	):
	page_translation_form.instance.page.translations.filter(
	language=language
	).update(status=status.PUBLIC)

Actual Behavior

The translation status is incorrect
