Mothballed ways renewed erroneously when loading a game

[Junna]

Latest compile. Ways mothballed will display, 'will be renewed with', and upon reloading, will have been renewed with functional tracks.

Thank you for the report: I have now pushed a fix in which mothballed ways do not have the same renewal way as the way that was mothballed. This will only apply, however, to ways mothballed after this fix is applied.
