So this is the heart of the problem.  I should have asked for:
 ls -l /dev/disk/by-path
too, but I think I know what it would show.

When your system identified your CD/DVDs as IDE, the hardware "path" was
pci-0000:00:09.0-ide-1:0.  Now that they're being id'd as SCSI, the path is 
pci-0000:00:09.0-scsi-0:0:1:0.  When the new symlinks were generated, it
didn't delete the old & obsolete rules.

I believe that if you simply
deleted /etc/udev/rules.d/70-persistent-cd.rules, on the next reboot it
would be built correctly.  BUT I HAVEN'T TESTED THAT!  So, you might want
to rename the file (to anything that doesn't end with .rules - or into
another directory), reboot, and see what you have.  If a new one isn't
generated, just rename the old one and reboot.
