TransfiniteInterpolationManifold: fix codimension one case
The codimension one case currently fails with an assertion:
This is triggered because we take a compatibility branch in case of
dim < spacedim
(ininclude/deal.II/fe/mapping_q_internal.h
):but still initialize the vector
unit_points
by a subdivided quadrature(which is needed for the default quadratic approximation; in
source/grid/manifold_lib.cc
):Fix this by simply initializing
unit_points
with the right number ofinterpolation points for the
dim < spacedim
variant.Closes: #13734
