t7700: test for promisor file content after repack

Add tests that check if the content of ".promisor" files are correctly
copied inside the ".promisor" files created by a `repack`.

The `-f` flag is used when repacking to ensure that all the packs
(created with `test_commit_bulk`) are repacked into a single new pack.
