CXFServlet does not correctly initialise when used from a war

[hbogaards]

The CXF plugin works correctly when we use it from gradle bootRun.

But when we create a war file and deploy that to a standalone Tomcat, the deployment fails due to duplicate initialisation.

Our application uses Grails 3.1.10
