Invoking reset() with autoPlay enabled throws exception

[TheHedge]

Invoking the reset() function in MediaPlayer.js results in the play() function throwing the "Missing view or source." exception.

With recent changes and issues in dash.js, autoPlay must be enabled (see issue # 1027 #1027). This results in the following sequence of events if reset() is invoked.

reset() sets source and element to null via the following.

    function reset() {
        //todo add all vars in reset that need to be in here
        attachSource(null);
        attachView(null);
        protectionController = null;
        protectionData = null;
    }

attachSource() invokes resetAndPlay() which then invokes play() if autoPlay is enabled.

play() throws an exception if element or source is not set.

The only way to use reset() at this point is to bracket all invocations as follows

    player.setAutoPlay(false);
    player.reset();
    player.setAutoPlay(true);

I think this is a duplicate of #974.
