Issue description

Current behavior: I had to change template of NbMenuItem. To do this, I downloaded menu component sources from Nebulars github. Then I modified paths in imports to include new one.

Now clicking on [nbContextMenu] element throws an error (context menu is not opening):

Importing forRoot in app.module doesn't fix this: https://github.com/akveo/ngx-admin/issues/1641
