partials/widget-content.php will never display the byline date

if the variable is set to false, then because ! empty( false ) === false, the fallback option of true is used.

This can be fixed by switching to isset( ... ) ? ... : ... ;, and making sure that where we use partials/widget-content.php, like in the Largo Recent Posts widget, we do so passing false explicitly.

This is the bug in INN/umbrella-voiceofoc#36.

The default behavior of the widget is to only save the positive, checked value, to assertively hide the date, so rather than testing for the absence of the negative value, should we not instead test for the presence of the positive value?
