`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.

Process and crop image in EditGroupChat.
This property is useful for clients to know when a channel or chat
was joined so they can use that to calculate the order of channels
and chats shown in applications.
Changes include a new joined property on the Chat struct,
as well as adjustments in the persistence layer to retreive and
update chat data in the database.
In addition there's a migration script that alters the existing
chat table to introduce a new column for the joined field.
It also updates all existing rows in the database to set `joined`
to `0`.
This commit introduces the following changes:
- `local-notifications` require as body an interface complying with
`json.Marshaler`
- removed unmarshaling of `Notifications` as not used (we only Marshal
notifications)
- `protocol/messenger.go` creates directly a `Notification` instead of
having an intermediate format
- add community notifications on request to join
- move parsing of text in status-go for notifications
LastMessage in chat was encoded in bytes so that we don't have to
encoded/decode everytime we save to db or pass the client.
An issue with emoji surfaced a problem with this approach.
Chat.LastClockValue represent the last clock value of any type of
message exchanged in a chat (emoji,group membership updates, contact
updates).
So when receving a new message, we should update LastMessage if the
clock of the LastMessage is lower than the received message, and we
should not only check LastClockValue, otherwise the message might be
discarded although it is the most recent.
This commit fixes the issue by keeping LastMessage as an object and
comparing LastMessage.Clock instead of LastClockValue
