AbstractPlaylist toString accidently append new line for inline uri parameter

[ishayhil]

Reproduce:

String playlistStr = "#EXTM3U" +
                  "#EXT-X-VERSION:3" +
                  "#EXT-X-MEDIA:LANGUAGE=\"eng\",AUTOSELECT=YES,FORCED=NO,TYPE=SUBTITLES,URI=\"https://foo.bar.com\",GROUP-ID=\"subtitles\",DEFAULT=YES,NAME=\"caption_1\"";

String resultPlaylist = PlaylistFactory.parsePlaylist(PlaylistVersion.DEFAULT, playlistStr).toString(); // the uri will be in new line instead of uri param.

You need to differentiate between inline uri and newline uri when parsing the playlist.
Will open you a PR with a possible fix
