`If a device list update goes missing, the server resyncs on the next one` was failing because a previous test would receive a `waitTime` of 1h, resulting in the test timing out. This now tries to handle the returned errors differently, e.g. by using the default `waitTime` of 2s. Also doesn't try further users in the list, if one of the errors would cause a longer `waitTime`.
