RPC: Do not return an error on 0 results

Return an empty array and set the result count to zero instead.

Before:

    $ curl 'http://localhost/rpc.php?type=search&arg=raboof'
    {"type":"error","resultcount":0,"results":"No results found"}

After:

    $ curl 'http://localhost/rpc.php?type=search&arg=raboof'
    {"type":"search","resultcount":0,"results":[]}
