refactor(theme): remove user context menu (#231)

BREAKING CHANGES: NbUserComponent no longer has context menu. We've
completely moved context menu in the separate component. So, to
migrate from the previous version you have to remove user menu items
```
<nb-user [menu]="items"></nb-user>
```
and use NbContextMenuDirective:
```
<nb-user [nbContextMenu]="items"></nb-user>
```
