merge 0.14.2-4 for additional fixes from Debian

The upstream case actually isn't important as Debian chose to disable it as well.
But we have a bunch of autopkgtest fixes which we want to retain.

Fortunately Debian now is on salsa, so I can more easily send it there this time.

Merge ready in https://code.launchpad.net/~paelzer/ubuntu/+source/spice/+git/spice/+merge/375496
with tests being fixed up for python3.

I think the tests should be dropped and suggested "Fix or Drop" to Debian in
https://salsa.debian.org/debian/spice/merge_requests/1

FYI: Uploaded

This bug was fixed in the package spice - 0.14.2-4ubuntu1
