Camel page does not automatically update for new or removed camel contexts/routes.

Issue

• In Hawt.io on a container that has a camel route running:
  1- Go to the "Camel" page and see that the Camel context is displayed.
  2- Go to the OSGI page and stop the bundle that contains the Camel route.
  3- Go back to the "Camel" page and see that the camel route is still there.
  4- Use browser "page refresh" (ctrl-F5) and see the context has now disappeared.

• Reproduction of this issue is easy and you can also run this scenario the other way around by starting a new bundle with a camel route, and then noticing that the camel tab does not show up until the whole page is reloaded.
