Replace Firefox with Chrome in selenium tests

functional tests with Firefox 35 are broken due this open FF issue:
https://code.google.com/p/selenium/issues/detail?id=8390

Chrome and FF 34 works well, but need to use Chrome because
we cannot pin FF to 34.0 in test instances. Chrome must be added
to test jobs also.
