fixes #6512 - move valid notices routes inside resources block

In Rails 3.2.8, it's not seeing the previous notice route get_new as
being part of the engine.  Moving inside a resource block fixes that
problem.  I also removed 2 routes that aren't valid and shouldn't exist
anymore - note_count and auto_complete_search.
Might want to add a :only=>[] to this, otherwise by default rails will automatically add 7 routes including create/update/index/
