fix a null assertion error when there are missing mandatory args in commands (#199)

Fixes https://github.com/dart-lang/args/issues/197

The 2nd argument to ArgParserException is supposed to be the command chain that it was parsed from and not the option (note this is handled separately as well) - this was causing the command runner to throw a null assertion error later on by passing the name of the mandatory option as the command name, which doesn't exist as a command.
