Fix PHP 7.4 warnings

Browse source 
If a db query returned NULL instead of an array, then accessing $row[0]
now throws a warning. The undocumented behavior of evaluating to NULL
is maintained, and we want to return NULL anyway, so add a check for the
value and fall back on the default function return type.
