Bug in example postgres model.js.

[IhorHryshkov]

module.exports.getAccessToken = function(bearerToken) {
  return pg.query('SELECT access_token, access_token_expires_on, client_id, refresh_token, refresh_token_expires_on, user_id FROM oauth_tokens WHERE access_token = $1', [bearerToken])
    .then(function(result) {
      var token = result.rows[0];

      return {
        accessToken: token.access_token,
        clientId: token.client_id,
        expires: token.expires,  // This position
        userId: token.userId  //And this position
      };
    });
};

Please fix it to:

module.exports.getAccessToken = function(bearerToken) {
  return pg.query('SELECT access_token, access_token_expires_on, client_id, refresh_token, refresh_token_expires_on, user_id FROM oauth_tokens WHERE access_token = $1', [bearerToken])
    .then(function(result) {
      var token = result.rows[0];

      return {
        accessToken: token.access_token,
        clientId: token.client_id,
        expires: token.access_token_expires_on,
        userId: token.user_id
      };
    });
};

Or:

module.exports.getAccessToken = function(bearerToken) {
  return pg.query('SELECT access_token, access_token_expires_on AS expires, client_id, refresh_token, refresh_token_expires_on, user_id AS userId FROM oauth_tokens WHERE access_token = $1', [bearerToken])
    .then(function(result) {
      var token = result.rows[0];

      return {
        accessToken: token.access_token,
        clientId: token.client_id,
        expires: token.expires,
        userId: token.userId
      };
    });
};

Could you take this code and create a PR for it?
