Clear the registration flag when we detect that our credentials have
been invalidated, but retain the knowledge that we've been registered
before, so as to preserve post-first-install behaviors like skipping the
introductory install screens, and accessing the main ui.

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.

The user-agent string includes the information needed (OS + Chrome version) and the console.get() function seems just right. The debugLog itself is not manipulated.
Only show sent_at for outgoing messages, matching Android.
The received_at timestamp reflects the time a message was saved locally.
It is necessary on both incoming and outgoing messages for sorting
purposes, but can be confusing in the context of an outgoing message
detail view, since users don't think about themselves "receiving" their
own messages, and may even interpret this as the time that a message was
received by their conversation partner's device.

This chrome alarm business is in place to help us wake up and check for
messages when running in the background. Without it, chrome will suspend
our app after a short period of inactivity. Upon waking, if the app
discovers it is not linked, it prompts you to link it. However, if
you've declined registration (i.e., because you already maxed out your
linked device limit, but chrome auto-added the app to another machine),
we should just wait until explicitly launched again.
