Finalize second execution phase.
When the export is executed "On-Client" at PDM, the add-in may request a
second execution phase by setting Handled to TRUE at OnSerializeForSecondPhase.
If so, OnSerializeForSecondPhase is invoked for current add-in allowing to prepare for consequent OnPreBatchProcessFile
-events by deserializing from SerializationData.
This event is invoked after all conversions are done and same original SerializationData also is available
during this event.
If a logger was created at OnDeserializeSecondPhase, then use that for logging. Otherwise use CreateLogger
to create one and log information about the process.
Handled determines whether or not all conversions were succesfull. OnQueryExportSuccess will be invoked as event for second phase.
