Summary
Improve the (perceived) responsiveness of onboarding a watch via the phone by showing a loading indicator after submitting to indicate it's doing something, and Snackbars for success/error.
On failure, sending the stacktrace over to the phone is also useful, for now I'm just printing to the log. Example:

Before (stable):

After (this PR):

Any other notes
Onboarding speed depends on the connection, sometimes it completes in less than a second while other times I'm waiting close to 10 seconds - obviously these improvements will be most interesting in the latter case.
