modify PublicApiRouter.js for fixing error

[Macifier]

please modify 172 line of PublicApiRouter.js to
var params = _querystring2.default.stringify({ username: username, token: token, id: config.applicationId, error: err.message, app: config.appName });
because you are sending error object to choose_password params url so it is getting error as empty if you send err.message atleast we can display error on choose_password if it doesn't match password criteria
