title: Cannot find RoutesBuilderLoader in classpath for tests with @SpringBootTest + @CamelSpringBootTest
body: <p>I have this multi module maven project <a href="https://github.com/ghitacornel/testApacheCamel" rel="nofollow noreferrer">https://github.com/ghitacornel/testApacheCamel</a>
  that i use for playing with Apache Camel.
  Here I wrote a route (camel.route.CsvJsonXmlRoute) and a test for the route (camel.CsvJsonXmlRouteTest).
  The route works fine.</p>
  <p>
  But when trying to run the test i get "
  Caused by: java.lang.IllegalArgumentException: Cannot find RoutesBuilderLoader in classpath supporting file extension: json"
  <p>
  It seems that @SpringBootTest + @CamelSpringBootTest do not get along fine. One does not load  Spring components, the other does not load RoutesBuilderLoader. 
  <p>
  Any idea on how to make the test working ?
