configuredfilePath being set, should not hit the network

Even if configuredfilePath is set, we still hit the CDN for the latest version.

node-chromedriver/install.js

Lines 51 to 54 in 700ba53

	promise = promise.then(function () {
	if (chromedriver_version === 'LATEST')
	return getLatestVersion(getRequestOptions(cdnUrl + '/LATEST_RELEASE'));
	});
