code: function getTasksFromTaskfile()
  {
      // tasks will already be loaded and are in the global collection so get it
      const tc = TASKS.globals.globalTaskCollection; 
      //this time the preloads come after the custom tasks - no choice
      const collection = TASKS.loadPreloadedTasks(tc);
      return collection;
  }
docs: In taskfile mode the tasks are defined before the mainline gets called through the
  use of the YAKE.task function. Hence by the time this function gets called
  those tasks are already in a global collection. So retreived them, add default tasks
  return the collection
  
  @return     {TaskCollection}  The tasks from taskfile.
