Fix T71712: Free the dynamic mesh preview when rebuilding the PBVH

Browse Source 
The PBVH usually is rebuild after a topology change, so it does not make
sense to keep the previous dynamic mesh preview vertex list. This may
cause a crash is the number of vertices of the new mesh (and preview) is
larger previous one. Now the list is deleted with the PBVH and a new one
will be generated using the new mesh when the cursor is updated.
