test: add two test cases for querystring

Browse Source 
+ Check an empty substring: In `querystring`, if the `maxKeys` is 1
  and the state machine finds an empty substring between separators,
  it should return an empty object.
+ Test invalid encoded strings: If provided string is an invalid
  encoded string in `query.parse`, it will not be encoded.
