Patryk Osmaczko 65be6f2b96 feat: add and distribute `chatIdentity.FirstMessageTimestamp` 
`FirstMessageTimestamp` enables members of the community to determine if
there are any messages they can fetch on the community channel(chat).

`FirstMessageTimestamp` is advertised by admin for each community chat
through `CommunityDescription`. It assumes admin is online frequently
enough to capture the first channel message.

For existing communities admin determines first message timestamp by
finding oldest chat message in its local database.

How to write migrations?

We only write up migrations, down migrations are not always possible in sqlite or too complex/too expensive. For example to remove a column you would have to duplicate the table, copy over the data, delete and recreated. This can be very expensive for some tables (user_messages for example), so should not be attempted.

Notes

One issue we faced multiple times is that updates to user_messages can be very expensive, leading to slow upgrade times and interrupted migrations. So avoid writes if not necessary.
