fix: do not set normalized name for existing chats and contacts in a migration

We got a report that application is not responding after update
on Android and getting killed before it can start,
suspected to be a slow SQL migration:
<#7602>

This change removes calculation of normalized names for
existing chats and contacts added in
<#7548>
to exclude the possibility of this migration being slow.
New chats and contacts will still get normalized names
and all chats and contacts will get it when they are renamed.
