chrome-mink-driver#158: Remove fallback efforts for missing windows

[minkphp/driver-testsuite#101](minkphp/driver-testsuite#101) has introduced test coverage which expects an exception if we attempt to switch to a window which does not exist. chrome-mink-driver previously tried to handle this by dynamically creating popups with `window.open()`, but we will now throw a DriverException instead.
