Comment 3 for bug 1838185

@Rene, do you know how this happened? The only way I can think of is that the project was opened with v4 of KiCad and then a new library was added using the old library list method. I didn't think it was possible to open a schematic in v4 once it was remapped. That is why I don't check for rogue library list entries after a schematic is remapped. I can add a check but I want to make sure there isn't some other code path that added a library to the old library list.
