The reason for the failing test is added deprecation warning to
`common_metadata` property of `ParquetDataset`:
```python
In [1]: import pytest
In [2]: import pyarrow.parquet as pq
In [3]: with pytest.warns(None) as record:
...: pq.read_table('v0.7.1.parquet',
...: use_legacy_dataset=True)
...: len(record)
Out[3]: 2
In [4]: record[0].message
Out[4]: DeprecationWarning("Passing 'use_legacy_dataset=True' to get the
legacy behaviour is deprecated as of pyarrow 8.0.0, and the legacy
implementation will be removed in a future version.")
In [5]: record[1].message
Out[5]: DeprecationWarning("'ParquetDataset.common_metadata' attribute is
deprecated as of pyarrow 5.0.0 and will be removed in a future version.")
```
As the `common_metadata` property is added to the `ParquetDataset`
constructor the warning is caught even if the property isn't explicitly used.
I will corrected the test to include the new warning and will keep the
change for `common_metadata`.
