Cron API: Remove unnecessary optimization getting ready events.

Browse Source 
Remove the check for future events prior iterating the array of crons in `wp_get_ready_cron_jobs()`. If there are no ready events, the `foreach` loop will break on the first iteration so the optimization is not required.

As WordPress Core adds a number of events by default, accounting for an empty array is not required in most instances.

Props lev0, jrf, SergeyBiryukov.
Fixes #56092.
