BUG: read_parquet doesn't accept anymore a file route starting with 'file://'
- [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.

---

```python
# Your code here
import pandas as pd
pd.read_parquet('file://<route_to_parquet_file>')
```

#### Problem description

When passed a path with the file protocol (e.g., `file:///home/Desktop/my_parquet.pq`) it throws the following error:

OSError: Passed non-file path: file:///home/Desktop/my_parquet.pq

#### Expected Output

Should read things fine. 

With Pandas 1.0.3 it does work perfectly, so there's something wrong when moving from 1.0.3 to 1.0.4.

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