Fixes for some test sentences

@ruiting this is about the "_advmod()" relationships.
In the link parser output "have" and "chairs" are connected with "\Op" and "fewer" and "chair" are connected with "\Dmcm"

I can see same relationships in these sentences. So I hope these sentences also would require "_advmod()" relationships.
He runs more miles than John does.   ----> "_advmod( run, more)"
He runs less miles than John does.     ----> "_advmod(run, less)"
He runs many more miles than John does. ----> "_advmod(run, more)"
He runs fewer miles than John does. ----> "_advmod(runs, fewer)"
