Task state DELAYED is not taken into account when finishing a workflow

[Renat Akhmerov]

Steps to reproduce:

wf:
  task1:
    action: std.noop
    policies:
      wait-before: 10

  task2:
    action: std.noop

If we run such workflow then as soon as task2 is completed the entire workflow will complete too and task1 will be ignored (because it will be in DELAYED state)
