Issue: Even after the canvas is deleted, the scheduler still continues to run the cached version of the canvas.
Note, this issue does not occur when the canvas is directly scheduled in the gallery, and only occurs when you schedule via the Designer on the controller directly.
Steps to replicate issue:
1) Publish a canvas into gallery
2)Schedule the canvas to run daily via the Designer --> Options --> View Schedules --> Select Controller --> Create new workflow and scehdule
3) Delete the canvas from gallery
4) You will notice that the canvas is still getting run on the defined schedule, even though you have deleted the canvas
