Make copy_nodal/elemental_solution() fail with the same error whether you are using opt or debug mode.
Make copy_nodal/elemental_solution() fail with the same error whether
you are using opt or debug mode.

MeshBase::elem()/node_ptr() assert in debug mode if an element/node is
not found, but return NULL in opt mode.  query_node_ptr() and
query_elem() return NULL in either mode, allowing the user to do his
own NULL checking.

Also fix one whitespace error.
