bug: BigQuery backend can't handle the empty result with json type

[goldmedal]

What happened?

When using the BigQuery backend, I found the Ibis can't handle the empty result if it's a JSON type.

The following code can reproduce it:

connection = ibis.bigquery.connect(
            project_id=info.project_id,
            dataset_id=info.dataset_id,
            credentials=credentials)
sql = "select json_object('a', 1, 'b', 2) limit 0"
df = connection.sql(sql).to_pandas()
print(df)

The output is

  File "pyarrow/table.pxi", line 4858, in pyarrow.lib.Table.from_batches
ValueError: Must pass schema, or at least one RecordBatch

The detailed log is provided below.

However, if the result isn't empty, it works well.

select json_object('a', 1, 'b', 2)

By the way, I also encountered a similar issue with the INTERVAL column. However, I have no idea to provide a simple SQL to reproduce it. 🤔
