Update sub-content.php

You're checking to see if the story snippets array is set and then is greater than zero OR the story intro is set and story isn't nothing and then going on to try to get things from the snippets array even though that might be empty due to the intro being filled.

Have put another check in later to ensure that the array actually exists and isn't blank as the other side to your check on line 56.

Should probably be two different loops.
