[fix] genius: add player an avoid exceptional programming

Add player:

- The players are just playing 30sec from the title.  Some of the player will be
  blocked because of a cross-origin request and some players will link to apple
  when you press the play button.

Avoid exceptions and (and BTW improve results)

-  ERROR   searx.engines.genius          : list index out of range
