adscanceled doesn't do the job

[michalk-k]

To be honest I don't know what is the intention of this event but found it not sufficient enough in case of problem reading/loading vast. By this I mean, I would expect video playback should start immediately when vast fails. But it doesn't - if getContent method fails, we have to wait a few seconds for ad timeout to see video playing.

By analyzing state diagram of videojs.ads I found we should trigger adserror event to play user video. However it doesn't work as expected until adsready is already called,

As quick mockup I added following delegate for adscanceled event:

player.on('adscanceled', function(){

        // Dirty. Without adsready adserror doesn't fire user video
        player.trigger('adsready');
        player.trigger('adserror');

    });
