…g peers (#7058) The race occurred as a result of a goroutine launched by `processPeerUpdate` racing with the `OnStop` method. The `processPeerUpdates` goroutine deletes from the map as `OnStop` is reading from it. This change updates the `OnStop` method to wait for the peer updates channel to be done before closing the peers. It also copies the map contents to a new map so that it will not conflict with the view of the map that the goroutine created in `processPeerUpdate` sees.
