Blob not found when iterating over container containing blobs in subfolders

[snorrea]

The following fails:

from cloudstorage.drivers.local import LocalDriver

storage = LocalDriver(key="./foobar/")
storage.create_container("foo")
container = storage.get_container("foo")
container.upload_blob("./todo.md", blob_name=f"12/1231/todo.md")
for b in container:
    print(b.path, b.name)

With the following trace:

FileNotFoundError                         Traceback (most recent call last)
~/.pyenv/versions/3.8.2/lib/python3.8/site-packages/cloudstorage/drivers/local.py in _make_blob(self, container, object_name)

    360         except FileNotFoundError:

FileNotFoundError: [Errno 2] No such file or directory: 'foobar/foo/todo.md'

During handling of the above exception, another exception occurred:

NotFoundError: Blob 'todo.md' not found in container 'foo'.

Is this expected behaviour? The file is created in subfolders as expected...
