PartDesign: [skip ci] remove automatic adjustment of view frustum when creating a body

In v0.17 this was needed to fix bug 2503 and was done with commit d4ff570bf9.
Now a more sensible view frustum is already set on document creation.

The automatic adjustment is even annoying now if the document is not empty and nothing is selected because
the view frustum can become too big and thus the objects appear quite small.
