With the privileged about content process enabled, we do a process flip when navigating between about:newtab and http://example.com/, which means that we might see the initial about:blank of the new DocShell load after the process flip and interpret that as http://example.com/ loading. This refactoring does two things: 1. Adds more documentation to E10SUtils.shouldLoadURIInBrowser, since it was being used kind of incorrectly in the test. 2. Makes it more explicit that we want http://example.com/ to load, and not any old page (like about:blank).
