    Fixes bug when importing a session where personIDs would already exist in the current database.
    
    The bug was that personSession wouldn't be imported. Now it avoids the
    duplicates but making sure that this personID exists for the current
    session (before it didn't import the personSession if the personID
    existed in the database (!))
    
    Pending: unit tests
