IgxGridState directive not able to reset columnList for igxHierarchicalGrid.

[hanastasov]

Description

Open dev samples

• igniteui-angular version: 10.1.0

Steps to reproduce

1. Open dev samples, go to State directive samples
2. Open hier grid
3. Move columns in the child grid
4. Save state
5. Restore state

Note: It seems that resetting the column list through grid.columnList.reset(newColumns), leads to trigerringonColumnsChanged, which triggers the event for the root grid:

igniteui-angular/projects/igniteui-angular/src/lib/grids/hierarchical-grid/hierarchical-grid.component.ts

Line 420 in d7ab1c1

super.onColumnsChanged(this.columnList);

, which eventually restores the columnList back to the autogenerated columns:

igniteui-angular/projects/igniteui-angular/src/lib/grids/grid-base.directive.ts

Line 4963 in d7ab1c1

this.columnList.reset(this._autoGeneratedCols);

Result

The column list is resetted as initially, instead of restoring to the saved state.

Expected result

The column list to be restoring of the saved state.
