Turn off viz output from test
Disable redistributing higher order nodes

This kills this feature if we're trying to do "fancy" higher order
geometric elements like the non-full-order types or the 3rd+ order
types, or if we're trying to fit curved boundaries... but it also is
necessary to make the feature usable in the first place with 2nd order
geometric elements.
Add a mesh redistribution regression test
Fix redistribution test_data file

I'd inadvertently committed only the header for a parallel restart
file before.
