    [stable-only] Add writer DB context to "add_provisioning_component"

    To ensure the "standardatributes" register is present during the
    creation of the "provisioningblocks" register, the method
    "add_provisioning_component" is wrapped with a database writer
    context. That will ensure the standard attribute ID, used as a
    foreign key in the "provisioningblocks" table, is present during
    the transaction.
