Fix frontend error on licensed variable products without attributes (v0.5.9)

Browse Source 
- Added null checks for get_variation_attributes(), get_available_variations(), get_default_attributes()
- Show informative message when product has no variations configured
- Changed product type check from instanceof to is_type() for better compatibility
