fix bug in gogs client

[da1nerd]

There is this bit of code

    /**
     * Performs a request against the api
     * @param partialUrl the api command
     * @param user the user authenticating this request. Requires token or username and pasword
     * @param postData if not null the request will POST the data otherwise it will be a GET request
     * @param requestMethod if null the request method will default to POST or GET
     * @return
     */
    private Response request(String partialUrl, User user, String postData, String requestMethod) {
        int responseCode = -1;
        String responseData = null;
        Exception exception = null;
        try {
            URL url = new URL(this.baseUrl + partialUrl.replaceAll("^/+", ""));
            HttpURLConnection conn;
            if(url.getProtocol() == "https") {
                conn = (HttpsURLConnection)url.openConnection();
            } else {
                conn = (HttpURLConnection)url.openConnection();
            }

That is incorrectly comparing strings. It should be if(url.getProtocol().equals("https")).
