Fix search results was not using the right url.

The search method was requesting an invalid url.
This was the cause of not returning the right anime/manga details.

It was only searching for the first word.

Example of the url atarashii requested: http://api.atarashiiapp.com/anime/search?q=mirai nikki
The way it should be requested: http://api.atarashiiapp.com/anime/search?q=mirai%20nikki
