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.
Ahh, I left this one alone on purpose, there is an active bug:  1121209  where we're waiting on an opinion from upstream.  It may turn out that the usage info is not printed at all in some cases, so then this test will need to be updated again.  I'm fine with just leaving it as failing for now, unless you think there's no harm in changing it twice (i.e. now and again when bug is fixed).  Maybe it's not a big problem.
