Ticket 47964 - v2 - Incorrect search result after replacing an empty attribute
Bug Description: when a replace operation for a nonexisting attribute is
done without providing new values the entry is stored
with incorrect meta data: an empty deleted value without
attribute deletion csn.
Fix Description: in the delete phase of the replace operation already create
the attribute to set the deletion csn. It would be created anyway
in the add part of the replace operation.
The function to calculate the required size to write the entry
needs also to be adjusted.
