[fix][ml]: subscription props could be lost in case of missing ledger during recovery

[nicoloboschi]

Motivation

During the recovery of the cursor, if the stored position points to a non existent ledger, the cursor is rewinded to the oldest position. In this case the subscription properties won't be stored in the managedcursor info on the metadata store

• Pass the cursorProperties instead of an empty map during recovery
