HLS: Don't merge on discontinuity, if it's the first segment 

How the m3u8 parser handles/groups #EXT-X to segment objects means the #EXT-X-DISCONTINUITY (`discontinuity` property) is tied to whatever segment is below it's line. Therefore, there's never a scenario where we need to merge+decrypt and the first every segment of the for loop, as there's no segments before it.

This can happen from just slightly off-spec playlists (can't blame it) but also from the OnSegmentFilter filtering out all segments before the first EXT-X-DISCONTINUITY. Common to happen when filtering out bumpers/intros.
