Comment:

 This is most likely caused by a plugin which has (intentionally or
 accidentally) added a value of false to the cron array. Even after
 deactivating your plugins, this value will persist.

 Unfortunately WordPress core can't protect against every possible invalid
 value in every option. I'm not sure that this is something that core
 should protect against. The PHP errors here are doing their job and
 alerting the user to a problem, which is their purpose.
