Remove BinaryCacheStoreAccessor

Probably as a result of a bad merge in
4b8f1b0ec066a5b994747b1afd050f5f62d857f6, we had both a
BinaryCacheStoreAccessor and a
RemoteFSAccessor. BinaryCacheStore::getFSAccessor() returned the
latter, but BinaryCacheStore::addToStore() checked for the
former. This probably caused hydra-queue-runner to download paths that
it just uploaded.
