Before this commit, when the user displays the subtasks list on a kanban
card and change the state of a subtask to set to Done then the
`closed_subtask_count` field does not changed in the kanban card.
This commit updates the `closed_subtask_count` when the subtask will
be closed or opened on the subtask list displayed in the kanban card.
Also, the `this.props.record.activeFields` is no longer used to fill in
the activeFields of Record component because the `activeFields` will
change in the future.
