fix/test #1753 fixing issues in tests following #1749

This commit fixes test issues which are happening following commit
8432f5b from #1749:
- SelectOnBlurSimpleRobotTestCase fails on Safari because a <select> in
Safari (on Mac) behaves differently than in other browsers (on Windows):
pressing the down arrow key opens the dropdown instead of only changing
the selection, as it is expected in the test
This test is now excluded from the test campaign for Safari.
- OpenDropDownFromButtonTestCase fails on IE 8 because SynEvents does not
faithfully reproduces the behavior of IE 8
This test was replaced by a robot test which correctly tests what is really
happening on IE 8
