While handelling multiple windows, if one is closed - switching to another gives a new browser session

[SydorenkoSergiy]

If selene handles multiple windows, and one of them is closed at some point (not by Selene), trying to switch to second window - will close the browser, and open a new browser session

selene==1.0.0a13

Steps to reproduce:

1. Given a browser_win1
2. Click on link (opens browser_win2)
3. Switch to browser_win2
4. Click on certain item in browser_win2 (window closes, as intended. Not by selene)
5. Try to switch to browser_win1

Actual result:
Browser_win1 closes. Opens a new browser session

Expected result:
Switching to browser_win1 and continue working

Image proof:
Before selecting an item, there are indeed two windows opened.

I got the same behavior if browser is crashing. I don't know exactly the reason but it's happening when i try to open new tab via link and switch to it. Selene makes a new local browser instance at this case, despite of remote driver using.
I'd prefer that selene falls with an honest error, and not disguised as a check error

Step to reproduce:

1. Set breakpoint on string "browser.should(have.url_containing('python.org'))"
2. Run code in debug mode
3. When breakpoint is reached, close browser by your self
4. Continue code execution
5. A new local browser instance is appearing

from selenium import webdriver
from selenium.webdriver import ChromeOptions

from selene.api import *


SELENOID_IP = '172.17.21.145'

options = ChromeOptions()
capabilities = {
    "acceptInsecureCerts": True,
    "enableVNC": True,
    "enableLog": True,
    "timeZone": "Europe/Moscow"
}
driver = webdriver.Remote(command_executor=f'http://{SELENOID_IP}:4444/wd/hub',
                          options=options,
                          desired_capabilities=capabilities
                          )

config.driver = driver
browser.open('https://python.org')
browser.should(have.url_containing('python.org'))
config.quit_driver()
