"Unique instance" doesn't work when packaged with flatpak

[mgautierfr]

Of fedora 34, if kiwix-desktop is installed with a rpm, when opening two zim files (by clicking on two zim files in the file browser), only one kiwix-desktop instance is launched (with two tabs). But if kiwix-desktop is installed with a flatpak, two kiwix-desktop instances are launched.

This is probably a communication problem between the two apps as flatpak runs applications in containers.

Same on Ubuntu... to me looks like a regression... as AFAIK this was working.
