paginate should return empty data when there have a bigger _page, but return last page data now

[byronogis]

"json-server": "1.0.0-beta.0".

Like there have 7 data in posts, and send:

1. /posts?_page=1&_per_page=5, that is normal.
2. /posts?_page=2&_per_page=5, normal too.
3. /posts?_page=3&_per_page=5, the response is not my expected, current is same with step 2, does there should got a empty array ?
