    metrolyrics: fix html parser
    
    Seems that in some lyrics a new <div></div> can be included with some
    info. That was breaking the html parser.
    
    Instead on relying on ending </div> for the lyric, let's use something
    else that is present and not so common (<p class="writers") as ending
    point for the lyrics and remove what is not interesting for us.
