Describe the bug

Installing a root accessing Appimage (e.g. Raspberry Pi Flasher Tool) a second time does not update its Desktop file entry in KDE

First Run installed to my User Folder /Applications

Second run from desktop menu prompts me to install again after asking for root It changes the location to /root/Applications but doesnt update the Desktop File Entry which still points to the old one.

Expected behavior

Make it delete and redo the entry when it detects that an entry exists in another registered location as my user folder / Applications

Steps to reproduce the issue

run appimage normally -> install

run from desktop menu -> asks for root password -> install prompts again -> install

desktop menu entry is now pointing to the old location where we prev run it from
