amplify-js: Invalid Refresh Token.

Bug.

Configuration:

1. I have set refresh token expiry to 3064 days
2. I have setting Device Tracking as ALWAYS

Code to refresh Session I have:

`if (cognitoUser !== null) {

            cognitoUser.getSession(function (err, oldSession) {
                if (!err) {
                    var refreshToken = oldSession.getRefreshToken();
                    console.log("Refreshing session");
                    cognitoUser.refreshSession(refreshToken, function (err, refreshedSession) {
                        if (!err) {
                            console.log("Session refreshed successfully!");
                            var logins = {};
                            logins[cognitoEndpoint + "/" + poolData.UserPoolId] = refreshedSession.getIdToken().getJwtToken();
                            AWS.config.credentials = new AWS.CognitoIdentityCredentials({
                                IdentityPoolId: identityPoolId,
                                Logins: logins
                            });
                            // Make the call to obtain credentials
                            AWS.config.credentials.get(function () {
                                console.log("Success credentials");
                                refreshingToken = false;
                                client = new AWS.CognitoSyncManager();
                                if (client) {
                                    client.openOrCreateDataset(bnDataSetName, function (err, dataset) {
                                        if (!err) {
                                            bnUserPreferencesDataset = dataset;
                                        } else {
                                            errorLogService(err);
                                        }
                                    });
                                }
                            });
                            deferred.resolve(true);
                        } else {
                            err.message = "ResumeAppplicationCognito: Not able to refresh session: User " + cognitoUser.username + ":" + err.message;
                            err.emailTried = cognitoUser.username;
                            if (!err.code.match(new RegExp(AppConst.exceptionsCodes.UserNotFoundException)) && !err.message.match(new RegExp(AppConst.exceptionsCodes.incorrectPassword))) {
                                errorLogService(err);
                            }
                            deferred.resolve(false);
                        }
                    });
                }
            });
        }`

I got this error due to some reason:

code: NotAuthorizedException, column: 1837305, emailTried: jo****@yahoo.com, line: 1, message: User jo****yahoo.com : Invalid Refresh Token., name: NotAuthorizedException, requestId: a64f28e6-2cd2-11e8-9102-45d988484951, retryable: False, retryDelay: 58.95665571402836 , statusCode: 400, time: 2018-03-21T06:39:48.215Z }
