So it [seems](https://askubuntu.com/questions/829370/n-ignoring-file-50unattended-upgrades-ucf-dist-in-directory-etc-apt-apt-con) it is a backup file, since a new 50unattended-upgrades is present.  
A `diff` of them shows

That is to say, the Ubuntu 14 version had  
`"${distro_id}:${distro_codename}";`  
as well as  
`"${distro_id}:${distro_codename}-security";`  
which is in the old and the new file.

So I deleted the backup/old file for now.
