FIX: Avoid duplicating e-mail body in summary e-mail (#27535)
We recently fixed a problem where secure upload images weren't re-attached when sending the activity summary e-mail.

This PR fixes that by:

Adding a failing test case for the above.
Moving the looping over multiple posts into #fix_parts_after_attachments! itself.
