toPlaceholders wrong behavior

[krava77]

Bug report

Summary

If an array value is empty toPlaceholders function does not clear the value in placeholder and leaves the previous value.

Step to reproduce

here is the result:

here is my code for the reproducing issue: $item = $object->toArray(); echo "<pre>Object Data: {$item['ends_at']} <br>"; $modx->toPlaceholders( $object, 'subscription'); echo "placeholder: {$modx->getPlaceholder( 'subscription.ends_at' )}</pre>";

Expected behavior

the function should clear the placeholder if the value is NULL or empty.
