If only mix and rendering one track, make the new track have the same name.

Browse Source 
This saves a lot of typing if it is necessary to render a lot tracks in-place whilst preserving their names.
It is currently impossible to test that the two channels of stereo tracks get the correct name, as making stereo tracks always results in tracks with the same name for both channels ... This code would be much simpler if stereo tracks were objects.
This function (Mix and Render) could be made simpler if it used the TrackList functions like GetNumExportChannels() and made better use of conditional iterators rather than working it out for itself.
