The Ewald surface-epsilon correction term is incorrect when molecules are broken over PBC.
It should be disabled in the 2020 release.

• Revision 2548c9e0 by Berk Hess on 2020-03-18T22:04:44Z:

Use WholeMoleculeTransform for orires and epsilon-surface

Remove direct use of the graph from the orientation restraint
and Ewald epsilon-surface term code by passing in whole molecules
created by the WholeMolecules class.
Since this was the only remaining use of graph in do_force(),
it can now be removed.

Also enabled the epsilon-surface mdrun-test.

Fixes #3441
