Correct misleading/confusing titles of if reference page

Previously, the "entity title" of the page was "if...else", but this page makes no mention of else. There is a separate page that documents else. The page title "if (conditional) and ==, !=, <, > (comparison operators)" is also unnecessarily confusing. There are separate reference pages for the comparison operators.
