fix(GODT-2390): Add reports for uncaught json and net.opErr

Report to sentry if we see some uncaught network err, but don't force
the user logout.

If we catch an uncaught json parser error we report the error to sentry
and let the user be logged out later.

Finally this patch also prints the error type in UserBadEvent sentry
report to further help diagnose issues.
