Summary: If a device disconnects and reconnects while keeping the plugin open, a new pluginInstance is available, but the React component would not be remounted since both the old and new pluginInstance have the same identifier (device/client/plugin). This change makes sure that if a different pluginInstance arrives, the rendering will be reinitialised as well.
