Don't throw cron job when some PayPal collection fails (#18795)

* Don't throw cron job when some PayPal collection fails

Follow-up of https://github.com/overleaf/internal/pull/18414 and https://github.com/overleaf/internal/pull/18572

This was causing `Heartbeat [cron-web-collect-paypal-prod] is expired.`
And the cron to rerun (altogether three times a day, instead of once a day)

* Update tests
