Cannot locate the config file under remote env

[luliangce]

current version find the config file(etc. python.json) from System's User Dir

get userSnippetFilePath(): string {
        let platform: string = os.platform();
        let AppDataPath: string;
        switch (platform) {
            case 'win32':
                AppDataPath = process.env['VSCODE_APPDATA'] || process.env['APPDATA'] || path.join(process.env['USERPROFILE'] || "", 'AppData', 'Roaming');
                break;
            case 'darwin':
                AppDataPath = process.env['VSCODE_APPDATA'] || path.join(os.homedir(), 'Library', 'Application Support');
                break;
            case 'linux':
                AppDataPath = process.env['VSCODE_APPDATA'] || process.env['XDG_CONFIG_HOME'] || path.join(os.homedir(), '.config');
                break;
            default: throw new Error('Platform not supported');
        }
        return path.join(AppDataPath, "Code", "User", "snippets", `${this.language}.json`)
    }

unfortunately, this didn't work well with vscode-remote environment.

i will try fix this in next few days.
