Actually the change has been made earlier, in 4.16.1+dfsg-5,
so 4.16.2+dfsg-1 also contains the change.  Here's the code
in the postinst script:

# remove old spool directory (point it to /var/tmp if in use)
if [ configure = "$1" -a ! -L $dir ] &&
    dpkg --compare-versions "$2" lt-nl 2:4.16.1+dfsg-5~
     if [ -d $dir ]; then
         echo "W: removing old samba print spool $dir" >&2
         rm -rf $dir
     used=$(testparm -s --section-name=printers --parameter-name=path 2>/dev/null || :)
     if [ $dir = "$used" ]; then
         echo "W: $dir is referenced in smb.conf [printers] section." >&2
         echo "W: redirecting $dir to /var/tmp. Please update your smb.conf" >&2
         ln -s ../tmp $dir

which should create symlink if we're upgrading from earlier
version (4.13 in your case) and the directory is actually
used in smb.conf (and not already a symlink).

I wonder.. if this code misses the case where this path is
referenced in another share? Where did you set this path in
