Build popcorntime from ci until yts movie outage is fixed

Currently the movie tab is broken. It's fixed in the experimental branch (master)

http://status.popcorntime.io/
> * Update - Issue with the subtitles API affects Release 0.3.7-2, Experimental builds are fine
>   May 13, 22:54 EDT
> [...]
> * Identified - The issue with the YTS API (Movies) seems to be related to a bad response for one of the movies. The movies page will continue to be intermittent until the issue is resolved.
>   May 10, 21:29 EDT
> * Investigating - YTS (Movies) is currently unavailable for Popcorn Time release 0.3.7-2, but is still working for the experimental builds. We're looking into what the issue could be and why it's only affecting release 0.3.7-2
