This might, hopefully, I don't know, possibly force the
database to live a little while longer and *reduce* but not
eliminate errors around stopping the database before we lose all
our DB::PG handles to it.
At the moment, the jobset object is unlikely to actually retrieve the
evaluation error output, because it isn't refreshed after
hydra-eval-jobsets is run.
Explicitly calling DBIx::Class::Row->discard_changes causes any updated
data to be refreshed, at the cost of losing any not-yet committed
changes to the row.
Set `dest_store` in the test hydra config, so that the testsuite ensures
that the distinction between the local store and the destination store
is properly taken into account.
Fix#938
By moving the tests subdirectory to t, we gain the ability to run `yath
test` with no arguments from inside `nix develop` in the root of the
the repo.
(`nix develop` is necessary in order to set the proper env vars for
`yath` to find our test libraries.)
