Delete folder with sub-folders not working

The Drupal\flysystem_gcs\Flysystem\Adapter\GoogleCloudStorageAdapter class contains a workaround for this issue in the upstream adapter library. This workaround doesn't currently seem to work, causing folders to be reported as non-existent while they do exist, causing them to not be deleted. I'll replace the workaround with one that does work, taken from here.

I was able to make GoogleCloudStorageAdapter::has even more efficient by reducing two network calls to one.
