Fixed the bug that the copied files were not deleted when the optimization failed

[overtrue]

When configured output_filepath_pattern which changed output path, the optimizer copied the file but doesn't deleted it when optimize failed.

today I create a demo with the following code:

require __DIR__ . '/vendor/autoload.php';

$factory = new \ImageOptimizer\OptimizerFactory([
    'output_filepath_pattern' => '%basename%/%filename%_optimized%ext%',
]);
$optimizer = $factory->get();

$filepath = __DIR__ . '/1.png';

$optimizer->optimize($filepath);

it copied two files:

.
├── 1.png
├── 1_optimized.png
├── 1_optimized_optimized.png

Thanks.
