Stop the server if generators specified for new worlds are not valid

Browse Source 
I thought I did this already in eff856d8e513a1f01eca16ab55bacf6e83399527, but it looks like my brain slipped a gear.

Without this change, it's possible to crash the server by specifying an invalid generator for the default world if it doesn't yet exist.
