The new tool osbuild-store-dump saves store.json to the current working
directory, with more or less arbitrary data in it.
This has been executed on osubild-composer-{12,13} (mutatis mutandis),
and the results are saved in `internal/store/test`. A new test is added
which loads these stores and does very basic verification on them having
been loaded correctly.
This is mostly meant to catch regressions that means old stores are able
to make composer crash, or lose all its data. It would not catch minor
errors that leave the stores syntactically correct.
