Adding a change of the same classification to the map will only add it as updateChange to the condenser info,
which means that the condenser info holds the first (updateChange) and the last (change) change of the same classification.
If there is an updateChange attached to the condenser info object and that change is already persisted,
that change will be used over the newest change.

@param {object[]} aCondenserInfos - Condenser info objects
@param {sap.ui.fl.apply._internal.flexObjects.FlexObject[]} aReducedChanges - Array of reduced changes
@param {object[]} aReducedIndexRelatedChangesPerContainer - Array with index related reduced changes per container
@returns {sap.ui.fl.apply._internal.flexObjects.FlexObject[]} Updated reduced changes
