AspectRatio: fix wrong orientation with locale
When setting a non default locale, the VideoPlayerActivity when in best fit aspect ratio will not update it's configuration.orientation when rotating, causing libvlc to assume that the orientation is still the one used when starting the video. By forcing the orientation to its new value in onConfigurationChange, this is fixed. Though it doesn't explain why it has this behaviour in the first place. This is a workaround.
Fixes #2475 (closed)
