RootView was using a legacy variable to redirect from the root of

Local Site. While this wasn't as big a problem on standalone Review

Board servers (it would end up redirecting to a non-Local Site URL), it

outright crashed RBCommons.
The proper variable for the Local Site is now used. Unit tests were

added to check for regressions. These uncovered an old query argument

used for login redirects, which no longer works. That query argument was

updated.

Unit tests pass.
Manually tested the redirects and that the old query argument didn't

work but the new one does.
