Specialize QofInstance* options set_value, catch validation exceptions.

Browse Source 
GncOptionValue<const QofInstance*>.get_value() returns a QofInstance* but
reports store them as strings, either commodity mnemonics or GUIDs.
Specialize set_value/set_default_value from scheme to handle those
possibilities.

GncOptionValidatedValue throws an invalid_argument exception if it's
fed an invalid argument. Catch that so that it doesn't crash the program.
