[fix][python] Task switch branch not show in webui (#12120)

when create task switch in python api, switch branch not show correctly,
due to we add some unnecessary attribute to switch task, this patch we
add `_task_ignore_attr` in class `Task` to ignore those unnecessary
attribute from `_task_default_attr`
