Better deal with strings in `switchWindow`

Is your feature request related to a problem? Please describe. Currently the switchWindow command iterates over all window handles and calls matches on url and title to see if the input matches it. This can be problematic if users use strings that contain a regexp character:

// works perfectly if you match like this
browser.switchWindow('google.com')

// doesn't work if you have a `?` character
browser.switchWindow('google.com?foobar=barfoo') // does not match the url e.g. https://google.com?foobar=barfoo

Describe the solution you’d like Let’s check if the command input is a string and use includes if so otherwise use match if it is a RegExp.

Describe alternatives you’ve considered n/a

Additional context This comes from a conversation I had with someone in Gitter stumbling over this.
