(maint) Update specs to use correct helper classes

 - Previously, specs were hardcoded to use the Win32::TaskScheduler
   helper during some retrieval and creation style tests, when they
   should be switching the class based on the appropriate helper,
   either PuppetX::PuppetLabs::ScheduledTask::TaskScheduler2V1Task OR
   Win32::TaskScheduler.

   This creates a minor discrepancy in a subsequent commit when
   additional testing is added for compatibility, which is implemented
   only in TaskScheduler2V1Task and *not* Win32::TaskScheduler
