was this missing before?  Would it make sense to move setting these properties
into the constructor of EncodedImage so we won't have to update the call sites?

EncodedImage is a horrible struct that is used in both Chrome and else where. So
updating ctor is not that easy. (pbos have a todo to clean this struct up but I
guess that todo will be left for the future).

I added it here to be able to test ViEEncoder, but it turns out ntp_timestamp is
not used by any real encoder implementations so I should probly not do that. It
is used by subclasses of EncodedFrame the receive side.

I refactored the test and is no longer dependent on any changes in this file.

     encoded.capture_time_ms_ = input_image.render_time_ms();
     encoded._frameType = (*frame_types)[i];
     encoded._encodedWidth = config_.simulcastStream[i].width;
