bug 1499057: webdriver: remove known web element cache; r=whimboo The known web element cache in the WebDriver test client, or webdriver.Session._element_cache, is used only to avoid constructing new webdriver.Element instances of the same web element and serves no practical purpose beyond that Since this client is intended for testing purposes, we would like to be able to construct duplicate webdriver.Element instances, so that e.g. fake elements can be constructed and send to the remote end. Depends on D9127 Differential Revision: https://phabricator.services.mozilla.com/D8855
