Unhandled exception when email limits are reached

[patrick-skamarak]

From Messaging.reserveSingleEmailCapacity docs:
If the transaction would cause the organization to exceed its daily email limit, using this method results in the following error: System.HandledException: The daily limit for the org would be exceeded by this request.

We recently had an incident where we hit org limits for Events. After that, we reached email limits. Adding a catch for System.HandledException would prevent Logger.saveLog() from halting execution when limits are reached.
