Fix T94624: Object as font instances don't work
The fundamental limitation is that we can only have one instance
("dupli") generator at a time. Because the mesh output of a curve
object is output as an instances, the geometry set instances existed,
replacing the object as font instances. The "fix" is to reverse the
order. The behavior won't be perfect still, but at least the old
behavior will be preserved, which is really what matters for a
feature like this.
One way to take this change further would be completely disabling
regular geometry evaluation while this option is active. However,
it doesn't seem like that would actually improve the state of the code.
