Wrong luacheck cwd is used with --config

[Nexela]

When a .luacheckrc file is automaticly detected it passes the cwd of the file. In this case the cwd of the .luacheckrc file should be used.

This rough js change allows it to work correctly

class Luacheck {
    constructor(coder) {
        this.coder = coder;
    }

    command(document) {
        const settings = this.coder.settings.luacheck;
        let args = [];
        let luacheckrc_path

        if (settings.automaticOption) {
            this.automaticOptions(settings, args, document);
        } else {
            const luacheckrc = path_1.resolve(settings.configFilePath, ".luacheckrc");
            if (isFileSync(luacheckrc)) {
                args.push('--config', luacheckrc);
                luacheckrc_path = path_1.dirname(luacheckrc)
            }
        }

        args.push(...defaultOpt);
        const fileName = uri_1.parse(document.uri).fsPath;
        args.push("--filename", fileName, "-"); //use stdin

        let cmd = settings.execPath || default_luacheck_executor;
        let cwd = path_1.dirname(luacheckrc_path || fileName);

        return {
            cmd: cmd,
            cwd: cwd,
            args: args
        };
    }
