An unhanded exception in RouteManagerBase _check_routepools

I meet an issue. A sample log is as follows

There is an exception, InternalStopWorkerException, introduced in https://github.com/Map-A-Droid/MAD/commit/7ea245ad9953d0498ab0198ab09aec401bd6d9c1. The exception is unhanded by the related route classes. After this happens, workers would not work again.
