Fixed a bug with the recordset status implementation to make it report
its status more accurately.
A recordset will now always report its highest priority state when it
contains multiple records. The order of priority is,
`ERROR`, `PENDING`, `ACTIVE` and `DELETED`.
See `bug 1842994`_ for more information.
