Fixed a couple console errors.

The language selection changes make it so that the reference language
is sometimes null.
Update angular to 1.2.7.

I originally did this to try to fix the loading issue.  It didn't
help, but it seems like upgrading makes sense anyway.
and some more webdriver test updates
Speedup the team activity page when filters are used

We were having an issue when the video language filter was used.  I'm
not really sure why, but it was changing how the mysql optimizer
handled the query and resulted in a filesort in a big temporary table.

Changed it so that we handle those filters as part of our subquery.
Refactored that code a bit and put it in the Team object instead of
ActionManager.  The main reason is that we now want to use TeamVideo
and we can't do that in videos.models because it's a circular import.

Fix task assign drop down #1919

The issue was USER_LANGS was not being set correctly anymore.  We
actually don't even use that variable now, so just remove it.
Don't cache the login link for anonymous users (#1921)

The link includes the request path, so we don't want to cache it.
It's cheap to generate in any case.
