REGTEST: add an extra testcase for ifnone-forwardfor

In GH #2187 it was mentioned that the ifnone-forwardfor regtest
did not cover the case where forwardfor ifnone is explicitly set in
the frontend but forwardfor option is not used in the backend.

Expected behavior in this case is that the frontend takes the precedence
because the backend did not specify the option.

Adding this missing case to prevent regressions in the future.
