Gracefully handle missing release. We are deleting it anyway, if it's already gone, that should not be an error.
Delete each release one at a time and report any errors at the end. helm delete when given a batch of releases does not attempt to delete each release and stops on the first error. Now when a release delete fails, it's safe to keep retrying the uninstall action until they are all deleted.
Removed double printing of error message. Cobra handles printing the error returned from the command, so we don't need it again in main.
