Subject: [PATCH] fix(jqLite): pass in a dummy event with triggerHandler

Previously, anchor elements could not be used with triggerHandler because
triggerHandler passes null as the event, and any anchor element with an empty
href automatically calls event.preventDefault(). Instead, pass a dummy event
when using triggerHandler, similar to what full jQuery does. Modified from
PR #2379.
