Issue description

When ngFor is used within an accordion body, the body does not resize appropriately when toggled. The body only seems to resize to static content.

Steps to reproduce:

Related code:

<nb-accordion>
      <nb-accordion-item>
                <nb-accordion-item-body>
                          <div *ngFor="let q of questions">{{ q }}</div>
                 </nb-accordion-item-body>
      </nb-accordion-item>
</nb-accordion>

Angular, Nebular
```
Angular: 6.1.7
Nebular: 2.0.0-rc.10

Problem solved by changing component implementation for NbAccordionItemBodyComponent to AfterViewInit rather than OnInIt in the nebular package.

EDIT: Just noticed that this change has already in commit 8c7953fa223ea1e6a2c06c408348e16d8ca75e9f though this commit is not merged yet.

Sorry can I confirm has this been fixed on the most recent stable release?

Hi @stubbsy345, no, unfortunately, but we hopefully will be able to make it in upcoming releases.

Hi, the solution provided does work when doing a ng serve but not when using --prod or --aot, because the ngOnInit function is then missing (which results in an error) and the ngAfterViewInit Function seems never to be called (and the accordion-item-body has no height). Do you have an idea to solve the problem?

Hi Guys,
I did a workaround to fix my code until we have a new version released.

I'm using just this peace of scss in the component I have the accordion.

/deep/ nb-accordion-item.expanded nb-accordion-item-body { .ng-trigger-accordionItemBody { height: auto !important; } }

I hope it will help u guys too ;)
