ResponseWriter should use sendError instead of setStatus

In the ResponseWriter the `setStatus(int, String)` method is used which is deprecated.

If used with Jetty as servlet container the message is dropped by intention and therefore no longer visible on the client.

See change: https://github.com/eclipse/jetty.project/commit/5d9c55be8f281c6c2e49825822413c6d203b1487#diff-bcf0034ba316615035f07846625ce33a55705a292049c63976c0393246d48b50

According to the deprecation hint `sendError` should be used instead.
