Test per-repo side panel config and re-application on repo switch

Exercises the path the live reload relies on: a per-repo lazygit.yml
sets a different side panel layout, and switching between repos
re-applies each one's own layout (the new-repo path for the cloned repo,
the cached-repo path on switching back).
