Fix dropdown menu does not open with firefox 34

Firefox update changed behaviour of the selenium tests, it is not
enough to click on the div representing dropdown menu region,
one must click on the first child (which is now button, but i suppose
it can change over time to input or anything else) in order to open the
dropdown menu.
