Score's part name (if present) linked when generating parts
If Add -> Text -> Part Name is used in a score (say to label it "Conductor's Score"), and then parts are created, each of those parts will have a part name "Conductor's Score" exactly on top of the part's own name.
Furthermore, that piece of text is apparently linked, like the title: deleting it in one part deletes it in all and in the score. But, if the same text is recreated in the score, it will not appear in the parts.

This is still a problem in 2.0.3.

Since part names are just generic "Text" elements like titles, composers, and a few other things, I guess the thing to do is to not link any text elements with a text of "instrument name (part)" that are found in the first frame (which we already special case, so we can generate one if necessary for the part name in the parts).
