plugin XEP-0384: run `profileConnected` workflow in background: XEP-0384 connection workflow can be very long when connecting after a while (due to OLDMEMO migration notably), which can lead to bad UX. It is not necessary to `await` it as `encrypt` and `decrypt` already wait for the plugin to be initialized correctly, so the workflow is now run in background.
