After update specs fail when there is an unexpected ajax query, because
the response is not an ajax response.
A long term solution is to remove mockjax from specs, because it makes
them brittle and they usually fail after small changes. A better
approach would be to use fixtures, which are available for ember model
When first sync template is displayed, user usually doesn't have any
repos, which also triggers rendering of getting started template. The
fix for this is to handle the action to render getting started page on
first sync and do nothing in such case.
I also added a test to ensure that it works correctly.
