Correct lookup with shared key and glob

Browse source 
Properly skip nodes and continue lookup when the key to be looked up
shares partial elements with others.

With the following scenario:

  tree = Radix::Tree(Symbol).new
  tree.add "/*glob", :catch_all
  tree.add "/resources", :resources
  tree.add "/robots.txt", :robots

When attempt to lookup for `/reviews`, it will now correctly return
`:catch_all` as found.

Fixes #23
