tests: add test demonstrating buggy path handling
`hg debugupgraderepo` is currently buggy with regards to path
handling when copying files in .hg/store/. Specifically, it applies
the store filename encoding to paths instead of operating on raw
files.
This commit adds a test demonstrating the buggy behavior.
