Why make the changes?
Mainly performance, those fields are almost always present in the
database but they are re-calculated on load by the client as it does not
have necessarily access to it.
What has changed?
- Remove `_legacy` persistence namespaces as it's a vestige of the
initial move frmo status-react to status-go
- Pulling chats is now a join with contacts to add contact & alias
