Fixing window switching on Selenium 3

[aik099]

Fixes this error from the #383:

Behat\Mink\Tests\Driver\Js\WindowTest::testWindow
WebDriver\Exception\NoSuchWindow: Unable to locate window:
Build info: version: '3.141.59', revision: 'e82be7d358', time: '2018-11-14T08:25:53'
System info: host: 'fv-az697-197', ip: '10.1.0.44', os.name: 'Linux', os.arch: 'amd64', os.version: '5.15.0-10[56](https://github.com/minkphp/MinkSelenium2Driver/actions/runs/8015977437/job/21897049068?pr=383#step:8:57)-azure', java.version: '1.8.0_292'
Driver info: driver.version: unknown

Implementation ported from the https://github.com/minkphp/webdriver-classic-driver.

What's included:

1. [fixed] switching to window by name on Selenium 3
2. [fixed] window resizing and maximizing for a non-current window
3. [added] closing all, but the main window during the session reset
4. [changed] the getWindowName and getWindowNames methods to return window names instead of window handles (if the name is empty, then the handle is returned)

Related issues:

• Missing tests for window resize/maximize by name driver-testsuite#94
• Added test to confirm, that opened windows are closed by the Session::reset call driver-testsuite#96
