Fix minor thinks in lots of tests. Mainly compatibility problems with new version docker

Important commit https://github.com/jzupka/autotest-docker/commit/0cb718dc5fbb30f6cd902ff88224561d6c73a1c0 fixes problem with generator of names.
This one has an active bug on it: 1097884  I un-verified it yesterday with a new reproducer.

IIRC, my change solved the ``commit_run_params`` problem slightly differently, we'll have to compare them more closely, maybe your way is better.
