Title: Added a catching of the SahiClient exception to wrap it in DriverException

Refs https://github.com/Behat/Mink/issues/473

The error message are not detailed because Sahi does not let SahiClient handle element not founds in a nice way (``findByXPath`` only gives you an accessor for the element, it does not perform any JS action to check whether this XPath matches)
