Happens when migrating from offline version 4 to version 7.

In offline migration v7 we clear/update the following tables (content_mail_index, mail_index, search_metadata, contact_index, search_group_data) without first checking if they exist.

Steps to reproduce:

• Login using V275.250324.1 of the app.
• Logout or close the app.
• Login with the same user using v299.250722.0 or newer.
• See the error.

Additional informations: The error is only shown once and does not appear again on subsequent logins once the user's offline storage has been migrated.

Test notes

• Issue no longer occurs and migrating offline storage from version 4 to version 7 works without errors.
