For reference issue 712754 dealt with the removal of PageClickTracker and PageClickListener from the codebase. For that to happen, we had to introduce some test only state into AutofillAgent, namely, |last_clicked_form_control_element*| and also made one method FormControlElementClicked() public. This was needed for "page_click_tracker_browsertest.cc" which is now "form_control_click_detection_browsertest.cc" to still work with the new refactor.

Eventually we should rid ourselves off of the added test variables. But this could involve changing the tests themselves. Essentially, one good idea is to use AutofillAgent::QueryAutofillSuggestions as a signal and/or perhaps use a mock AutofillDriver for that matter.
