### Describe the bug, including details regarding any error messages,
version, and platform.
`pyarrow.csv.write_csv` works as expected, but when the first record batch
in a table is empty, it writes two headers (on 2 different lines) instead of
one:
```python
import pyarrow.csv
import pyarrow as pa
import io
table = pa.table({"col1": ["a", "b", "c"]})
with io.BytesIO() as fp:
pyarrow.csv.write_csv(table, fp)
fp.seek(0)
assert fp.read() == b'"col1"\n"a"\n"b"\n"c"\n'
with io.BytesIO() as fp:
pyarrow.csv.write_csv(pa.concat_tables([table.schema.empty_table(),
table]), fp)
fp.seek(0)
# THIS IS WRONG:
assert fp.read() == b'"col1"\n"col1"\n"a"\n"b"\n"c"\n'
```
