Cron API: Modify `_get_cron_array()` to always return an array. 

Change the return type of `_get_cron_array()` to an empty array if the `cron` option is either missing or of an 
unexpected type.

This change ensures the return value for no registered events is consistently an empty array. Previously the return 
value could be either an empty array or `false`.

Props thakkarhardik, jrf, costdev.
Fixes #53940.
