3.5.2 - Minor changes and fixes

* removed search paths for Chrome Canary and Chrome Beta from find_chrome_executable()
    since chromedriver is always behind schedule so that means a driver for newer versions than current main could not be found and raises Exception.

* Changed/Fixed wrong binary version caused by patcher.
  Due to multi-threading people and a mistake fromy my side,
  the driver binary currently on disk was always used instead of getting new ones. even if you did not use multithreading.
  so even outdated binaries where kept!
  for multithreading people, it now only keeps the most recent binary and throws away others.
  for normal people, you will get the binary you deserve ;)

* Added more descriptive exceptions when Chrome binary could not be found origin
  no connection could be made to Chrome.

* some stuff i forgot
