Relates to #33108, but with a twist: save_as_mainfile messes up texture paths from textures linked from a library blend file.

How to recreate:

Download the attached sample.tar.gz, unpack and open the project/user_in_parentdir.blend file. (Alternatively, open project/shot/subdir_user_in_subdir.blend for the same effect)
Hit F12 to render, you should get a plane with a picture on it.
Run the following in the python console (replace /tmp path with something else if you're on Windows):

  `bpy.ops.wm.save_as_mainfile(filepath="/tmp/copy.blend", copy=True)`

Hit F12 to re-render, and you get a purple plane where there used to be a picture.

This can be analyzed in Python:

>>> for img in D.images: print(img.filepath)

... 

//../txtr/kermit.jpg

>>> bpy.ops.wm.save_as_mainfile(filepath="/tmp/copy.blend", copy=True)

{'FINISHED'}

>>> for img in D.images: print(img.filepath)

... 

//txtr/kermit.jpg

As copy=True was used, it looks like an error that any path has changed at all, especially the path of a file referenced by a library.
