----------------------------+-----------------------------
 The WP_Filesystem_FTP and WP_Filesystem_FTPext classes create temporary
 files during put_contents operations, but if the FTP connection is invalid
 or null, the method throws an exception without cleaning up the temp file,
 resulting in orphaned files in tmp.on busy sites you can easily end up
 with 100K files in matter of days not to mention the fact that the file
 name provided is not respected.

 For example lets say you pass/var/www/html/wp-
 content/uploads/plugin/index.php

 If ftp is not configured you will end up with:/tmp/plugin-{random
 string}.php

 And then the FTP will throw exception and the file will remain
