    Description

      The myxwiki.org upgrade produce tons of the following

      2022-06-29 09:48:00,732 [XWiki initialization] WARN  o.m.j.m.s.ErrorPacket          - Error: 1049-42000: Unknown database 'pom'

2022-06-29 09:48:00,732 [XWiki initialization] WARN  o.x.u.i.d.DocumentUserManager  - Failed to check if document [pom:XWiki.HengleyUpsewly] holds an XWiki user or not. Considering it's not the case. Root error: [SQLSyntaxErrorException: (conn=1392092) Unknown database 'pom']

      The reason is that a lot of user filter preferences were containing references to (spam) users from the wiki "pom" which does not exist anymore.

      It seems to be missing a check on wiki existence somewhere (probably in DocumentUserManager#exists, it does not make any sense to produce a warning for such a case, it should simply return false).
