DataGrid include deleted and persistence

[hannesb]

When using the IIsActiveRow/IIsActiveDeletedRow feature and grid persistence, persistSettings() should be called when the 'include deleted' toggle is clicked.

Workaround in ...Grid.ts:

    protected createIncludeDeletedButton(): void {
        super.createIncludeDeletedButton();
        // Call persistSettings() after user clicked on IncludeDeletedToggle
        this.toolbar.element.find(".s-IncludeDeletedToggle").click((e) => {
            if (this.gridPersistanceFlags().includeDeleted !== false) {
                // Detect if click event was triggered by user and not by restoreSettings()
                if (e.originalEvent != null) {
                    this.persistSettings(null);
                }
            }
        });
    }
