What happened?

When table schema is updated, it calls BigQuery.updateTable with PATCH method. With bigquery-emulator, it is returning the updated schema, however, google-cloud-bigquery plugin expects tableReference with tableId in the response. Link to the plugin function.

What did you expect to happen?

To have [tableReference][tableId] in the response.

How can we reproduce it (as minimally and precisely as possible)?

Install the python plugin: $ pip install google-cloud-bigquery (tested on latest version, 3.20.1, and old version 2.34.3).

Execute the following code:

from google.auth.credentials import AnonymousCredentials
from google.cloud import bigquery

client = bigquery.Client(client_options={"api_endpoint": "http://0.0.0.0:9050"}, credentials=AnonymousCredentials())

# change project id, dataset name and table name
table_ref = ".".join([GCP_PROJECT_ID, DATASET_NAME, TABLE_NAME])
table = client.get_table(table_ref)

# slightly modify `table.schema`
table = client.update_table(table, ["schema"])

It will give the following error:
KeyError: 'Resource lacks required identity information:["tableReference"]["tableId"]'

Anything else we need to know?
