manage.py delete_unused_files leaves UploadedFile instance

[sebhaase]

The last step in my FileFormMixin.save() is to call self.delete_temporary_files() which removes the duplicate file copy in temp_uploads and deletes the corresponding UploadedFile instance.
When I comment that line out and call instead manage.py delete_unused_files from the Linux command line,
it also removes that same file in the file system but it leaves the UploadedFile instance pointing to a non existing file.

I will have a look.

This is being fixed: #395.

Note that the delete_unused_files command should delete records that are created at least one day ago.

This is now fixed in master.
