InvalidArgumentException when no logger is set

[beheh]

An Exception is thrown when no Logger is passed to ConsoleRunner::createHelperSet, which is the default in cli-config.php.

This is due to Command::getResque always calling Symfony\Component\Console\Command\Command::getHelper('logger'), which in turn throws an InvalidArgumentException.

Command::getResque's if doesn't make any sense in this context, it should rather be testing for $this->getHelperSet()->has('logger').
