[Tests] Remove testfilteredcompositenode from this release

testfilteredcompositenode fails to compile. There is a fix in the current
development branch, but that one is hard to backport, and in this release,
there are no direct users of FilteredCompositeNode in PDELab, so the fix
can wait until the next release.

writable access to their ordering as part of the update() method as
implemented in PowerCompositeGridFunctionSpaceBase, but the necessary
accessor methods were missing in the derived classes.
