fix(delete, upload): Fixed Delete and Upload action behaviour

[vigneshd332]

Changes

• Deleting the image only hid it from view, fixed it to remove it from the canvas entirely so the canvas is cleared.
• Made the default "No file uploaded yet" message appear when there is no image on the canvas
• Uploading a new image without deleting the old image causes issues, fixed that by forcing a delete of the old image when a new image is uploaded so an overwrite can be done.
• Delete action is now added to change control so an image deleted by mistake can always be undone.
