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
There was a bug on status-react where it would save filters that were
not listened to.
This commit adds a task to clean up those filters as they might result
in long syncing times.
This commit also returns topics/ranges/mailserves from messenger in
order to make the initialization of the app simpler and start moving
logic to status-go.
It also removes whisper from vendor.
