Check if api_result exists or call Spice.failed 

Fixes #1347 

+ Check if api_result exists or call Spice.failed for the following Spices: bbc, brainy_quote, forvo, game_info, mass_on_time, plos, bootic, coupon_mountain, newint, npm
+ Brainy Quote: Fix indentation **Edit: Strange the indentation appears fine on the original file :sheep:**
I think this should be `'plos'`?
