Must apply verbose comments to kinetics that are averaged in estimateKinetics()

For rate rules that get created during
fillRulesByAveragingUp, the kinetics comments retain
verbose information about kinetic sources.
However, if averaging is performed during the
selection of best kinetics in estimateKinetics(), this
information was not retained, so it must be added here.
