Rate content permission is not ported to D8

We didn't want anonymous users making ratings in my recent project so I used CSS to disable the stars. This is not so solid as someone can disable the properties from the browser and make a vote, but my client is okay with it as not many people would think we disabled the stars in the frontend.

First I added the user roles in the template variable and then used this CSS,

.user-role-anonymous .fivestar-widget .cancel,
.user-role-anonymous .fivestar-widget div.star,
.user-role-tutor .fivestar-widget .cancel,
.user-role-tutor .fivestar-widget div.star,
.user-role-administrator .fivestar-widget .cancel,
.user-role-administrator .fivestar-widget div.star {
  cursor: not-allowed;
  pointer-events: none;
}

Repatch from #24 for 1.x-dev.

#31 works for me. Thanks!

I tried to resolve this issue. Tested it on D8, working fine. But not able to figure out the root cause of the pipeline failure.
