Internal server error if search would return no results

[twof]

example:
https://package.vapor.cloud/packages/search?name=asdfasdfsdfasdf&limit=10
returns

{
    "reason": "Something went wrong.",
    "error": true
}

Issue is here. I think it ought to return an empty array instead if there are no results

Edit: Actually that shouldn't be causing the issue we're seeing since that wouldn't throw a 500
