Wladimir J. van der Laan a365ed03c0 Merge #20683: test: Fix restart node race 
fab46b34f4b13abbb0af276c3fb548f25ccc28bd test: Fix restart node race (MarcoFalke)

Pull request description:

  It is not allowed to start a node before it has been fully stopped. Otherwise it could lead to intermittent issues due to access issues (e.g. cookie file https://cirrus-ci.com/task/6409665024098304?command=ci#L4793)

  Fix that by waiting for the node to fully stop.
