Removed search icon from faq list and admin controls

[rt4914]

Explanation

This PR simply removes the search icon from FAQListActivity and AdministratorControlsActivity. The search icon was not functional and therefore its correct to remove it for now and introduce it when we implement the whole functionality.

Just to check, why is this removed?

[rt4914]

The search_icon was part of menu_faq_list_activity which is an independent xml file.

This function onCreateOptionsMenu helps to bind the menu_faq_list_activity to the Activity/Screen so that we can show the search icon in header/toolbar.

As we have removed the search_icon, it means that menu_faq_list_activity will be empty, therefore we remove it too which means we don't need to bind it to activity anymore.
