fix: cannot read property of undefined in sampleclient.js line 42

Added: line 32. All tests passed.

const keyFile = require(keyPath);
keys = keyFile.installed || keyFile.web;

oauth2.keys.json when downloaded looks like this:
{"installed":{
"client_id":"",
"project_id": "",
...
"redirect_uris":[...]}
}
