Allow change position after MediaEnded event

Description of Change

Allow change position after MediaEnded event

The report-status-timer in this PR is:

• started in OnMediaOpened (when a new media opened successfully)
• stopped in OnSourcePropertyChanged (when opening a new media or setting media to null)

This will keep the status/positioning/progress-bar alive until the media is set to null or a new media is loaded, but dragging the progress-bar-position to the end, will not stop the status/positioning/progress-bar from being alive.

I'm pretty sure we have a good reason to keep the timer. So removing it doesn't look like the right solution

This PR is not removing the timer... it's keeping it active :)

The timer is started in OnMediaOpened

And we never stop the timer?

Ah, good point. OK, the ClearTimer is back. MediaElement will now stop the timer when setting the media source to null.

@jfversluis can you take a look at this PR and make sure that it's fine to change the behavior of the timer? I believe this will be a breaking change anyway.
