allure-selenide doesn't work correct with Selenide 5.x multi-browser function in some cases

[vinogradoff]

allure/allure-selenide 2.12.1

Beginning with Selenide 5.x WebDriverRunner.getWebDriver() can delivery the wrong webdriver depending on configuration, if multiple browser are used in a single test.

Also screenshot logger crashes trying to make a screenshot when open (=WebDriver.get(url)) function fails to open the browser session correctly.

Reproducible example for the second case:
