Fixed issue 06172: Update to Version 1.92+ from 1.91+ Cannot Complete - Reason: Duplicate column name 'grelevance'
Dev Problem was that some upgrade attempts added grelevance column, but aborted while running UpgradeConditionsToRelevance() before setting the upgraded DBVersion
Dev Users who continue to have this problem on upgrade should manually change their DBVersion to 154 in the settings_global table (so that LS knows that grelevance was added), then let the automatic DB upgrade process run again.
