PixelPaint: Make PaletteWidget::set_image_editor take a ImageEditor*
After closing the last open ImageEditor, selecting a color would try to dereference it causing a crash. Instead make set_image_editor() take a pointer to it and set it to nullptr when closing the last tab like we do with LayerListWidget and LayerPropertiesWidget.
