test(portals): match the movie detail's icon-only favorite button

The Xtream movie detail's favorite control is now an icon-only button, so
the shared "add this detail to favorites" helpers no longer found it by
class. They are used against series and Stalker details too, which still
render the labeled variant, so they now select by accessible name — the
icon button carries the same label in aria-label.
