Accordion directive ignores Input Id

[TheCell]

Bug description:

I think this is a bug. The new ngbAccordion is a directive. We usually set our own unique Ids for ngbAccordionItems (previously panels) but with the new system the Input for id is overwritten.

It seems as if line 193 in https://github.com/ng-bootstrap/ng-bootstrap/blob/master/src/accordion/accordion.directive.ts private _id = `ngb-accordion-item-${nextId++}`; is ignoring whatever @Input('ngbAccordionItem') set id(id: string) has as input at the start.

Link to minimally-working StackBlitz that reproduces the issue:

Working Example
You can see that I set a custom Id in the template but it's ignored when I log it to the console or display it in the template.

Versions of Angular, ng-bootstrap and Bootstrap:
