`Blob.from_string(gs_url, client=client)`: TypeError: Client.__init__() got an unexpected keyword argument 'parent'

[fnkr]

In the current version, when creating a blob using Blob.from_string() and specifying the gs://bucket/path URL as well as the client, the following error is thrown once we want to retrieve the object (e.g. using blob.download_to_file()):

Traceback (most recent call last):

Example code:

import io

import google.cloud.storage
import google.cloud.storage.blob
from cloud_storage_mocker import Mount
from cloud_storage_mocker import patch as gcs_patch

storage_dir = "."
bucket_name = "b"


with gcs_patch([Mount(bucket_name, storage_dir, readable=True, writable=True)]):
    client = google.cloud.storage.Client()

blob_name = "hello.txt"

# Write object
blob = client.bucket(bucket_name).blob(blob_name)
blob.upload_from_string("world")

# Make object using `Blob.from_string()` and `gs://` URL
blob = google.cloud.storage.blob.Blob.from_string(f"gs://{bucket_name}/{blob_name}", client=client)

# Workaround: Recreate blob using `client.bucket().blob()`
# blob = client.bucket(blob.bucket.name).blob(blob.name)

# Read object
stream = io.BytesIO()
blob.download_to_file(stream) # <-- throws exception
stream.seek(0)

There's a workaround though: after parsing the gs:// URL using Blob.from_string(), we can create a new blob using client.bucket(bucket).blob(blob), which works.
