* Cleanup app state on initialization error When returning an initialization error, the app state was not cleaned up. This is especially visible during tests, as `appCount` is not decremented, and makes the new app initialization fail. * Test the `platform server` command As the `platform server` command only exits when interrupted by a signal, it is not possible to test it as the other cobra commands. Instead we directly test the actual command function. The internal command handler is slighly refactored to take a channel in argument, and registers it as the signal handler. Nothing very different—except than controlling this channel from the outside allows the test to send the system signal itself, thus preventing the server to run forever.
