This fix corrects the implementation of the nearest neighbor Coulomb V interaction for the Kagome Hubbard Model and adds a test. Now the reversed matrix element is always added. Previously this happened only when -r != r, which missed the reversed orbital element for -r = r.

Code looks fine, and the test is not just a todo. As far as the physics goes, I have not independently worked this problem but trust @maierta.
