Relocated store URI is reported as 'local', wrong

[roberth]

Describe the bug

The store location in an error message is wrong. See steps.

Steps To Reproduce

There's probably an easier way to trigger this.

1. Choose or make an unimportant store path <path>
2. Back up a store path with nix copy --to ~/recoverstore <path>
3. Corrupt the original store path by mounting the system store file system rw and deleting it from the file system. Do not delete it from the store db; we want that entry to remain.
4. sudo nix store repair --extra-substituters ~/recoverstore --extra-trusted-substituters ~/recoverstore <path> (the latter option seems to have no effect; need ?trusted=true; different issue)

Observe a message like

warning: ignoring substitute for '/nix/store/nzb7spdhiy30ikv1crnk8dgl0svyjgw4-libunistring-1.2' from 'local', as it's not signed by any of the keys in 'trusted-public-keys'

Expected behavior

warning: ignoring substitute for '/nix/store/nzb7spdhiy30ikv1crnk8dgl0svyjgw4-libunistring-1.2' from '/root/recoverstore', as it's not signed by any of the keys in 'trusted-public-keys'

nix-env --version output

2.24.10

Additional context

• More material problem in this scenario is nix repair does not adhere to extra-trusted-substituters #11875

Yeah I think it doesn't render query params, and that is the normal form. Maybe my store reference cleanup branches can help with this...
