[client-app] Prevent old N1 config from getting wiped when installing Nylas Mail

Summary:
Due to a legacy migration system, users that had previously installed
old N1 (1.5.0) would get their N1 config wiped after installing Nylas
Mail (2.0) in most cases.

See https://github.com/nylas/nylas-mail/blob/n1-pro/src/browser/nylas-pro-migrator.es6 for details
