If self-update fails because the downloaded file cannot be renamed or copied, it is left wherever it was downloaded to. Because it was always given the same name (
composer-temp.phar), this didn't seem much of a problem - and could allow the user to manually move it if things got hairy.However, it is now given a randomized name (3bb78fd) which produces multiple files, so this fix deletes the downloaded file on self-update failure.
