Applied same changes as on EvaluationSetup on DebugEvaluationSetup:

- doubled timeout time for opening connection
- fail the test if the connection is timed out
- added printStackTrace() in all cases where it was missing

Also added a bit more info to the printed messages.

Additionally, added assertions in setUp() about evaluation context and
vm.
