With the 4.0 network rewrite I introduced a regression in 094e1d70dee1.
It only covered the case where a checkpoint is restored via --import.
The normal restore path was not covered since the static ip/mac are now
part in an extra db bucket. This commit fixes that by changing the config
in the db.
Note that there were no test for --ignore-static-ip/mac so I added a big
system test which should cover all cases (even the ones that already
work). This is not exactly pretty but I don't have to enough time to
come up with something better at the moment.
Fixes#16666
