v0.10.3

• [#97] Patches the "Stop in background" feature (see the stopInBackground option of Sever.constructor()) to avoid unhandled promise rejections if server crashes during such auto-stop (auto-restart), and there are state listeners connected to the server (we assume they are handling such errors). It still leaves such promise rejections unhandled if no state listeners are connected (e.g. that allows optional instrumentation, like Sentry, to detect and report these unhandled rejections, attracting attention to possible issues with the host app).
• Updates dependencies.
