[TASK] Switch to chrome in ac tests

The acceptance tests currently rely on firefox esr build
and younger firefox versions don't run with given web driver.

The patch updates selenium dependency to youngest version,
adds chrome webdriver as dependency, hands over some start
arguments to chrome and fixes a couple of tests to stabilize
the acceptance tests with chrome.

Goal is a quicker acceptance tests execution with chrome
instead of firefox. Furthermore, it is now much easier to
execute the acceptance tests locally since just a "current"
chrome version is needed instead of an outdated firefox nobody
has installed by default. Additionally, chrome strives for
a headless version in its current dev build, which is an
additional option for the tests later to drop another dependency.
