Visit helper not returning correct content upon using this.replaceWith for redirection #204
Description
Currently, the Visit helper returns <body><h1>Redirecting to ... as DOM content instead of the DOM of the route to which the initial route redirects using this.replaceWith.
The issue is happening at this returned value - https://github.com/embermap/ember-cli-fastboot-testing/blob/master/index.js#L86
As fastboot provides the html content based on the statusCode and if it is a redirection getting redirection text - https://github.com/embermap/ember-cli-fastboot-testing/blob/master/addon-test-support/index.js#L46
I think for testing the finalized body should be provided by using page.domContents().body as HTML content.
