Subject: [PATCH] [Addressability] Update route without reinstantiating

Work around normal behavior of Angular when path changes;
instead of reinstantiating controller for Browse mode
when Browse-initiated path changes occur, act as if the
route hadn't changed (so that the URL updates but the
currently-displayed state, e.g. tree expansion, is
preserved.) WTD-1149.
