Use customized `PanelLayout#removeWidget` and `PanelLayout#insertWidget` logic for the layout updates. The customized functions ensure no side effect if adding/removing the widget to/from the layout but it's already present/absent. Unlike the default [`PanelLayout#removeWidget`](https://github.com/phosphorjs/phosphor/blob/9f5e11025b62d2c4a6fb59e2681ae1ed323dcde4/packages/widgets/src/panellayout.ts#L154-L156) behavior, do not try to remove the widget if it's not present (has a negative index). Otherwise, required widgets might be removed based on the default [`ArrayExt#removeAt`](https://github.com/phosphorjs/phosphor/blob/9f5e11025b62d2c4a6fb59e2681ae1ed323dcde4/packages/algorithm/src/array.ts#L1075-L1077) behavior.
