Add guards to program, subcategory and activity batch updates

[andriokha]

Hi! I saved a program subcategory and received the following error. I believe it's because there were no associated activities.

TypeError: count(): Argument #1 ($value) must be of type Countable|array, null given in /var/www/html/web/modules/contrib/openy_features/openy_node/src/BatchNodeUpdate.php on line 82 #0 /var/www/html/web/modules/contrib/openy_features/openy_node/src/BatchNodeUpdate.php(82): count(NULL)"

Btw this is a complete tangent, but I was wondering about using batch_set() in a hook_node_update(): will the batch be processed if you update a node programmatically rather than via a form?

Merged, thank you

yes, batch works in programmatically node->save() contexts
