setBestSolution is called to check any solution.  That message was
really intended when a solution was branched to.  In that case the node
is discarded.  For strong branching solutions or heuristic solutions,
there is no effect on the node.

I have modified in trunk only (as it is not very important) so message
only happens if CBC_SOLUTION.
