Subject: [PATCH] Fixed a bug in the update of the backend when the Spiral Vase
 option is enabled / disabled.

Spiral Vase forces different kind of slicing than the normal model:
In Spiral Vase mode, holes are closed and only the largest area contour is kept at each layer.
Therefore toggling the Spiral Vase on / off requires complete reslicing.

This commit moves the update to the correct location.
