Bug 9226: Wrong branch filter after suggestion creation

Signed-off-by: Owen Leonard <oleonard@myacpl.org>

Before the patch, upon submitting a new suggestion in the staff client I
was redirected to a view which was not filtered by branch. After the
patch I was redirected to a view which was filtered by my logged-in
branch.
