BUG: Empty dataframe with valid index object is not being read correctly via parquet reader
- [x] I have checked that this issue has not already been reported.

- [x] I have confirmed this bug exists on the latest version of pandas.

- [ ] (optional) I have confirmed this bug exists on the master branch of pandas.

**Note**: Please read [this guide](https://matthewrocklin.com/blog/work/2018/02/28/minimal-bug-reports) detailing how to provide the necessary information for us to reproduce your bug.

#### Code Sample, a copy-pastable example

```python
In[38]: df = pd.DataFrame(index=pd.RangeIndex(0, 10, 1))
In[39]: df.to_parquet('a')
In[40]: pd.read_parquet('a')
Out[40]: 
Empty DataFrame
Columns: []
Index: []
In[41]: df.to_parquet('a', index=True)
In[42]: pd.read_parquet('a')
Out[42]: 
Empty DataFrame
Columns: []
Index: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
In[43]: pd.read_parquet('a').index
Out[43]: Int64Index([0, 1, 2, 3, 4, 5, 6, 7, 8, 9], dtype='int64')```
```

#### Problem description

When `index` is `None`/`True` parquet reader must retrieve only `RangeIndex` and not empty `RangeIndex` or `Int64Index`.

#### Expected Output
We should be able to get rangeIndex when we read from parquet file `a`.

#### Output of ``pd.show_versions()``

This could be related to https://github.com/pandas-dev/pandas/issues/37896, but it appears the parquet reader is also not able to retrieve any Index at all when `index` is `None`. Hence filing this as a separate issue.
