Gmsh background mesh doesn't work in parallel

[guyer]

r5253 introduced a test for Gmsh remeshing which fails in parallel.

This wasn't caught originally because Buildbot had a pervasive svn checkout failure for some reason.

The expected result is

but instead we get

I think the order of the values sent as the background are somehow out of sync with proper positions in the mesh.
