Because remote clients will delete all sessions in response to an end
session message, regardless of which device it came from, when our
linked device sends an end session message, we must also end all
sessions with the destination.
This change moves the end session flag processing to processDecrypted,
which is shared between handlers of sent messages, data messages, and
messages which are re-tried after resolving identity conflicts.

Help debug bad session errors by logging some envelope info about the
message we are about to decrypt. With this, if there is a decryption
error (e.g., bad mac or no session) it is clear from the logs what
number and device message sent the bad message.
Also log when we send and receive end session messages and when we close
sessions for certain devices.

Sometimes an error is thrown while processing groups from a group sync
message. We still want to fire the groupsync event when we're done
handling all the data, even if some of it was bad.
We should not ack envelope protobufs that fail to decode correctly. If
the server happens to send us such a thing it probably indicates a
protocol mismatch between it and the client, in which case the client
needs to update and re-receive the failed message.

Follow up to b0da4910. When inferring membership of the sender in an
unknown group, remember to save and return the group members.
Generally, this should only effect standalone clients unless someone
managed to clear their groups db table, since linked clients get group
info synced at registration.

This may increase processing latency a bit, particularly with large
attachments, but will ensure that messages are dispatched in the order
they are received.
It would be nice to enforce ordering on only the dispatch step, so that
we could, for example, decrypt the next websocket message while waiting
for an attachment to download, but that will require a more complicated
refactor. Will stick with the quick fix for now and revisit later.

Websocket resources should have their keepalive timers reset whenever a
message comes in. This is a nicety that slightly reduces the amount of
traffic we send when actively messaging.
Previously this was handled by MessageReceiver, but it's a bit cleaner
to just have the WebsocketResource add an extra 'message' event handler.
// FREEBIE
This ensures that the containing promise is rejected without triggering
the side effects of an uncaught exception, such as causing the debugger
to pause.
// FREEBIE
`tryMessageAgain` is the routine called when re-trying a message that
failed to decrypt due to an IncomingIdentityKeyError. This handling
needs to move to MessageReceiver because it depends on
`processDecrypted` to handle incoming message protos, which depends
on a server instance in order to download attachments.
