Current behavior
DataTable - Paginator, when current page reach the first or last page. The "move to first" or "move to last" icon in the paginator looks disabled. But when you click the disabled icon, whole application been redirect to the default route.

Expected behavior
The clicking disabled "move to first" or "move to last" page icon should do nothing.

Minimal reproduction of the problem with instructions
The demo page of official site: https://www.primefaces.org/primeng/#/datatable/paginator
Click the |< icon after open the page.

Please tell us about your environment:
Chrome 60.0.3112.113

• Angular version: 2.0.X
  Demo site

• PrimeNG version: 2.0.X
  It's the official site demo page, so I would assume it's the latest version.

• Browser: [all | Chrome XX | Firefox XX | IE XX | Safari XX | Mobile Chrome XX | Android X.X Web Browser | iOS XX Safari | iOS XX UIWebView | iOS XX WKWebView ]

Chrome 60.0.3112.113

@stevenxi I have created a pull request to fix this issue. It was caused by not preventing the default event for the button click when you were already on the first/last page.
