New unit test fixes

New unit test fixes following sentences
He runs more often than John.
He runs less often than John.
He runs here more often than John.
He runs here less often than John.
He is faster than John.

@linas @ruiting I have added above rule"ADV!_3" to form "_advmod(often, less)" relationships. e.g. sentence "He runs less often than John."
So what is our conclusion, should I keep it or remove it?
