fix: Fix bees leaving their beehives with disabled `natural_mob_spawning`

[ByteExceptionM]

Overview

Bees that are in nests will not be able to get out of them, because the event will be canceled if the configuration natural_mob_spawning is disabled. No new entities will be spawned - the entity already exists, but is only in the beehive. To work around this you would have to enable natural_mob_spawning so far, but this results e.g. in entities being spawned as well when generating chunks. I think the best solution is to remove the check for beehives here to make this possible again.
