Tomcat Stacktrace is rendered as response

See original GitHub issue

When we use problem-spring-web with tomcat servlet container and WITHOUT https://github.com/zalando/logbook we encounter the following behaviour:

Request with specified unsupported Accept header:

curl -v -H "Accept: text/xml" http://localhost:8080/hello
> GET /hello HTTP/1.1
> Host: localhost:8080
> Accept: text/xml

Results in the following response:

< HTTP/1.1 500
< Content-Type: text/html;charset=utf-8

When you include https://github.com/zalando/logbook and enable trace logging <Logger name="org.zalando.logbook.Logbook" level="trace"/> the stack trace won’t be rendered anymore inside the response and the response code changes from 500 to 406.
