[Multi Material] Fix first layers of prime tower when using "no sparse layers" (#2764)

Browse source 
* MM - Add check for first layer

* Change: If no sparse layer is on -> Respect the toolchange in the first-layer checkup, to use a brim and slow down printspeed if using a primetower

* Fix comment
