Error while playing content in v1.24.3

[tuxes3]

While trying to get the integration data for an InteractiveVideo content (with one Single Choice Set) the following error occurs:

property_exists(): Argument #1 ($object_or_class) must be of type object|string, array given

While investing further into this error I found that an unused if statement is causing this. https://github.com/h5p/h5p-php-library/blob/1.24.3/h5p.classes.php#L4037

Commenting out the if solves the error and everything is working as intended.

Here my patch:
