'plugin_delete_result' transient deleted instead of "plugins_delete_result_$user_ID" in /wp-admin/plugins.php

[jdgrimes]

The results of plugin deletion are stored in the "plugins_delete_result_$user_ID" transient. This transient is checked on /wp-admin/plugins.php after plugins are deleted in case there were any errors. It attempts to delete the transient after retrieving it from the DB, but it does not properly append the user ID to it:

$delete_result = get_transient( 'plugins_delete_result_' . $user_ID );
		
delete_transient( 'plugins_delete_result' ); // Delete it once we're done.
