resourceloader: Avoid escaping of UTF-8 characters in messages

It's not needed to escape UTF-8 characters in messages.

The characters '&', '<' and '>' are still escaped. For the output in
load.php this escaping is not necessary but messages can also embedded
into <script> tags and here are the characters '<' and '>' problematic.
