Failing test for 2293

Uses the WUI to edit and add a package to a group, then it renames the
group before checking how many datasets it has.  The call via sqlalchemy
shows it has the correct number of datasets, but the index page shows the
wrong number as we've changed the name without re-indexing the datasets
