Fix for Hourly Crons (#1127)

* Fix for Hourly Cron

We should be using whereTime instead of whereDate

https://laravel.com/docs/8.x/queries#additional-where-clauses
`The whereDate method may be used to compare a column's value against a date`

* Fix for RemoveExpiredBids

I used where to do check 'cause people may set 48 hours to remove a bid, thus neither whereDate nor whereTime will give a correct results.

* Fix for DeletePireps

I used where to do check 'cause people may set 48 hours to delete cancelled or rejected pireps, thus neither whereDate nor whereTime will give a correct results.
