Title: Fixing error when No file was uploaded (or presumably other UploadError)

Without this fix I get the following error when trying to upload without selecting a file

```Warning (2): Invalid argument supplied for foreach() [CORE/Cake/View/Helper/FormHelper.php, line 682]```

```
}
$tmp = array();
foreach ($error as &$e) {
```

```$error = 'No file was uploaded.'```
```
