Technical analysis:

• Issue has happened around here
  when trying to restore settings, but when we don't anymore have the older locale mapping object
• It is from UserInfo table, locale setting is used and not from Settings table, and hence the developer can decide to remove the column after making sure about absence of its usages.

AC:

• Find out how other fast syncs were not failing all these time and only this is failing
• The above issue should never reoccur

Notes

• It is from UserInfo table, locale setting is used and not from Settings table, and hence the developer can decide to remove the column after making sure about absence of its usages. => We store the selected locale in userInfo, but have a link to all Org allowed Locale infor from Settings.locale

• First time fast-sync done after app install does not fail, the issue happens only when we do reset sync by clearing data and then we attempt to perform Fast sync
