Filtering movies with the same title using year (fix https://github.com/worr/node-imdb-api/issues/13 https://github.com/worr/node-imdb-api/issues/14)

I'm aware of https://github.com/worr/node-imdb-api/commit/cbda1abbc68595ffad6a319f009cf91879fc5a0c but the API might come back one day
Fixes https://github.com/worr/node-imdb-api/issues/13 and https://github.com/worr/node-imdb-api/issues/14
