Database updates

In the /admin/dbsync page the administrator can check if any update was not successful and, if so, retry it.

If an update has failed but doesn't register as failed for some reason, the administrator can attempt to re-execute the update. For example for DB update #1999, by visiting the webpage:
https://hubzilla.com.bradmin/dbsync/1999
