    Return immediately from qof_book_destroy if hash_of_collections is null.
    
    If qof_book_destroy is called on a QofBook* freshly created with
    qof_book_new (usually because it was used to create a session that now
    must be destroyed) it would try to empty the non-existent hash tables,
    crashing.
