The "errors" section was defined twice in this file, the first one was
the once being removed here, another one is at line 164 (before removal)
or line 158 (after removal).
The content of duplicated strings definition are totally the same, the
second part has more data (41 lines in total, compare to the removed 6
lines), so I removed the first part but not the second part.

This new table will be used to store the external_dashboard_url which
allows users to add a link to their external dashboards (ex Grafana)
to the Metrics dashboard.
The columns 'Created on' and 'Last activity' have been
added to the admin -> users view.
Sorting options have also been added for last activity
and the search bar has been moved to match the issues
page.
