[renamerOnUpdate] Expand scope of prevent_title_performer to remove duplicate when $title is before $performer

This only prevents duplicates if $performer is before $title, but some people have the $title before the $performer, such as {$studio}.{$date}.{$title}{.$performer}.

Remove duplicate text when $title is before $performer. This is applicable for a lot of scenes that use the performer name as the title.

I implemented something like this for my own use with the previous version of the Script.

It would prevent outputting the Performer if the Performer name was in the title.

I also implemented something to skip the Performer if the Performer name was in the file path.

I'm going to have a look at this now in the new version, and will speak to @Belleyy if it is of any use.
