Project conversion cq rescue fails for V5 to V6 even though both -cache and -rescue libs are available.

Description

When I open a project made in KiCad V5 in KiCad V6 the "rescue dialog" appears. Clicking on [OK] fails to work and I get the dreaded [??] symbols in the schematic. However, when I click on [Cancel] during the "rescue" process, then KiCad just reads the schematic symbol graphics from either the projects -cache or -rescue library and the schematic looks complete.

Why does it even trigger the "rescue" process when the [Project]-cache.lib is available?

Steps to reproduce

1. Open the attached project in KiCad V6.
2. Open Schematic editor from the project menu.
3. Click [OK] in the "rescue" dialog. (Now you see the [??] symbol for the capacitor.)
4. Close Schematic Editor without saving.
5. Open Schematic Editor again, but now Cancel the rescue dialog.
6. KiCad reads the capacitor symbol from "somewhere" and the schematic looks normal.
