Set initial stream to be played to first entry in M3U8 playlist

According to HLS especficiation we should play initially the first item
in the m3u8 playlist:
"The first entry in the variant playlist is played when a user joins
the stream and is used as part of a test to determine which stream is
most appropriate. The order of the other entries is irrelevant."
