Not only this code is unnecessary with the new way selected
aspects are stored, also on some edge cases could confuse the user
for example when having two tabs opened and hitting refresh in one
of them. Expecting selected aspects, but the "a_ids[]"-like url could
instead set the new group of selected aspects.
This becomes a problem when having this widget
instantiated looking at the followed_tags stream
With the former code de/selecting aspects was
only refreshing the followed_tags stream, not
loading aspect stream posts
With previous css selector two textareas where
returned, causes reset of the post text when
selecting new aspects for the second time on
the left nav. Related to #2102
