prevent RPC walletpassphrase returned bad answer

[wwwcase]

Correction in rpc.js#51 (in function send) it was like this: if (!result.data['error'] && result.data['result'] != undefined) result.data = result.data.result; else result['success'] = false;

became so (walletpassphrase is succes when result.data:{"result":null,"error":null,"id":"curltest"}) : if (!result.data['error'] && result.data['result'] != undefined) result.data = result.data.result; else if (!result.data['error'] && result.data['id'] != undefined) result['success'] = 'success'; else result['success'] = false;
