mstask/tests: Work around race conditions with the task scheduler process.

When a task is created the process scheduler locks and loads it. This can cause ITaskScheduler_Delete() to fail with a sharing violation if it is called at the wrong time. Just retry a bit later when that happens. This fixes failures mostly in Wine but also in Windows 10 from time to time in both task and task_scheduler.
