[//]: # NOTE: This repository only maintains packages that are listed in the Readme. Please make sure that your issue is directly caused by one of these packages and if not file an issue in the correct 3rd party package repository.

Environment (please complete the following information):

• WebdriverIO version: 7.0.5
• Mode: Standalone mode
• Node.js version: 12.18.4
• Yarn version: 1.22.10
• Browser name and version: Chrome 88
• Platform name and version: Mac 10.15.7 (Catalina)

Describe the bug When using browser.url(url); I am getting this error message when running remotely via Browserstack

   "TypeError [ERR_INVALID_URL]: Invalid URL:
     at onParseError (internal/url.js:256:9)
     at new URL (internal/url.js:332:5)
     at new URL (internal/url.js:329:22)
    at Browser.url (/xxxxx/node_modules/webdriverio/build/commands/browser/url.js:43:17)"

locally its working as expected.

To Reproduce

// navigate to a new URL (local and browserstack)
browser.url('https://webdriver.io');
// receive url
console.log(browser.getUrl()); // outputs: "https://webdriver.io"

Expected behavior The given url should be received both locally and remotely.

@larryg01 the problem was that the base url was an empty string. I created a PR with a fix that ensures that empty strings are ignored.
