I found the commit that caused the bug that caused me to do the last
revert. I'm therefore reverting the previous revert and I will be
committing a revert that reverts the commit that introduced the bug. See
next commit.
This reverts commit db2d38a7af.
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
* if user is logged out, the default tab should be 'recent'
* when user logs in, the tab is switched to 'my repositories'
* when user logs out, my repositories is hidden again and tab is
switched to 'recent'
