How to reproduce

Give a Flatpak App with Flatseal permission to talk to a invalid DBus Name (e.g Test).

Expected Behavior

Everything should work. It should print a Warning that this Permission is invalid and ignored, but that's all.

Actual Behavior

The App do not start. It give you this Message when you try to run in terminal:

Error: Invalid dbus name test

That makes the App completly unusable until you reset the Permissions. Thats even worser when you do it on global.

flatpak override didn't allow this:

$ flatpak override --talk-name=test
Error: Invalid dbus name test

But it is still possible to set this Permission by editing the file in the overrides directory, what is what Flatseal does. Flatpak should not rash in that case.
