Current behavior
DataList component, when property [paginator] is set to false and [paginatorPosition]='both' remains displayed

Expected behavior
should be hidden

Minimal reproduction of the problem with instructions

1. declare a 'p-dataList'
2. set [paginator]=false;
3. [paginatorPosition]='both'

Where exactly if fails
DataList Component;
Lines:
TopPaginator: *ngIf="paginator && paginatorPosition!='bottom' || paginatorPosition =='both'"
BottomPaginator *ngIf="paginator && paginatorPosition!='top' || paginatorPosition =='both'"
should be
TopPaginator: *ngIf="paginator && (paginatorPosition!='bottom' || paginatorPosition =='both')"
BottomPaginator *ngIf="paginator && (paginatorPosition!='top' || paginatorPosition =='both')"
