Title: Fix accidental type conversion in sluggable behavior.

This generated code:

$slugNum = substr($object->getAccountId(), strlen($slug) + 1);
if (0 == $slugNum[0]) {
$slugNum[0] = 1;
}

return $slug2 . ($slugNum + 1);

will turn `$slugNum` into an array if substr returns false. By checking
with `===`, this is avoided.
