fix we need a path error

[ghost]

Commit 4ef9254 (Add tslint validation.) renames path to pathKey, but misses
one usage of the variable. This leads to the following error:

AssertionError [ERR_ASSERTION]: we need a path
    at JSONPath.query (...\node_modules\jsonpath\lib\index.js:92:10)
    at KubeConfig.applyAuthorizationHeader (...\node_modules\@kubernetes\client-node\dist\config.js:174:59)

Ugh, clearly we need better testing sigh

Thanks for the fix.

Somehow, the change is not in 0.5.2:

$ curl -s -S https://registry.npmjs.org/@kubernetes/client-node/-/client-node-0.5.2.tgz | tar xzO package/dist/config.js | grep path
const path = require("path");
const jsonpath = require("jsonpath");
                    if (config['cmd-path']) {
                        let cmd = '"' + config['cmd-path'] + '"';
                        let pathKey = config['token-key'];
                        pathKey = '$' + pathKey.slice(1, -1);
                        config['access-token'] = jsonpath.query(resultObj, path);
        const config = path.join(process.env.HOME, '.kube', 'config');
