Fixing minor typo
Avoid variable reuse

Renaming the $output variable when we assign the Twitter response value
because reusing a variable is a bad practice.  It easily leads into
unintended consequences.  Eg:

    // Assign the output object to my class
    $this->output = $output;

    // ... insert code here ...
    // Now override $output with Twiter
    $output = $response->toValue();

    // ... insert even more code here ...
    // Let's show either a brief status or a more in-depth line.
    // A bit atypical to do this, but perhaps there's a good reason.
    if ($this->output->getVerbosity() == OutputInterface::VERBOSITY_NORMAL) {
        $this->writeln("Processed $count records");
    } else {
        $this->writeln("Processed $count records in $elapsed seconds");
    }
