Fix all possible quality changes containers for single extrusion

In the current fix, the quality changes that are applicable to the
machine may not have been fixed yet because they are not active at that
moment. This commit makes sure that for a single extrusion machine which
has just been updated to have an ExtruderStack, all the quality changes
containers that are applicable to this machine will be updated as well.
