So far, if the writer for a subgraph encounterd an error, it would stick around as 'poisoned' for as long as the process lived. That made it impossible to restart a subgraph (possibly after clearing some external error condition) With this change,
SubgraphStore.writable
will create a new writer if the old one has been poisoned.
