Retry policy doesn't work when task was rerun

[Vitalii Solodilov]

As Mistral user I expect that number of retry times will begin with 0 when I rerun task.
For example, workflow:
version: '2.0'
wf_fail:
  tasks:
    task1:
      action: std.fail
      retry:
        delay: 0
        count: 5

When workflow was failed for the first time I see 6 created action executions, as had been expected.

But when I rerun the task only one action execution will be created.
