This resolv.conf is generated by openresolv based on information
NetworkManager sends. And looking at the resolvconf code, this is a bug
in openresolv 3.7.3 which ships in Debian unstable, and has been fixed
in openresolv 3.8.0:

So it looks like Debian should update openresolv, or at least grab that
patch.
