    Avoid LB ERROR status on delete when LS/LR are already deleted

    The delete operation of an LB lists all references to it (LS and
    LR) and in a single transaction deletes them together with the
    LB itself. If any of those deletions raise a RowNotFound exception,
    the execution will report ERROR status.

    This patch will reduce those situations, rechecking the command
    that triggers the RowNotFound exception and passing in case a LS
    or a LR was the culprit, deleting finally the LB and reporting as
    a DELETED status. In other case, the exception is raised and
    finally the LB will be reported as ERROR status.
