The `Run Program` step's PrePlanRun should not check if the working directory exists

In this case I have another Run Program step that creates the directory that is then not found.

14:07:39.754  TestPlan     "Run Program" PrePlanRun completed. [125 us]
14:07:39.754  TestPlan     PrePlanRun of 'Run Program (1)' failed with message 'The directory C:\Users\romadsen\projects\opentap\sdk\Examples\bin\Debug could not be found.'.
14:07:39.754  TestPlan     Exception: The directory C:\Users\romadsen\projects\opentap\sdk\Examples\bin\Debug could not be found.
