Continue workflow for given WorkflowObject id (oid).

    Depending on `start_point` it may start from previous, current or
    next task.

    Special custom keyword arguments can be given to the workflow engine
    in order to pass certain variables to the tasks in the workflow execution,
    such as a task-id from BibSched, the current user etc.

    :type start_point: str

    :return: UUID of the workflow engine that ran the workflow.
