"Years" filter returns no results outside `years=1902-2037`

When executing
```
https://api.trakt.tv/movies/popular?extended=full&limit=20&page=1&years=1902-2037
```

the API returns several search results normally. However anything outside this range, e.g:

- 1901-2037
- 1902-2038
- 0-9990

**return no results**.
