Reviewed by Eric Carlson.

When WebKit receives the AVPlayerItemDidPlayToEndTimeNotification notification, it still
attempts to estimate the current time because it believes it is still playing, as it hasn't
yet received the -timeControlStatus KVO. Reset the values for currentTime estimation when
receiving this notification so that the values returned are consistent.
