Logging exception (CANNOT_OPERATE_ON_DELETED_CAMPAIGN_ADEXTENSION) in listener on Rate exceeded error

When we are updating a call/location extension, if RateExceeded Error occurs then it is logging CANNOT_OPERATE_ON_DELETED_CAMPAIGN_ADEXTENSION exception for debugging (As per dev comments) but the functionality works fine as expected. As Exception will leads to confusion and it should be handled.

Steps to replicate

Step 1: Create an account with ad extension.
Step 2: Verify the tables related to ad extension.
Step 3: Update the Call/Location field.
Step 4: Verify the tables related to ad extension.
Step 5: Check the listener log.[Throws following exception when retired with RateExceded error]
