BUG: mypy doesn't understand the ~ operand for Series
- [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.

- [x] (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
# save it like test.py
import pandas as pd

s = pd.Series([False])
print(~s)
```
then running `mypy` on this code I get the following errors:
```bash
$ mypy test.py
test.py:3: error: Too many arguments for "Series"
tesrt.py:4: error: Unsupported operand type for ~ ("Series")
```

#### Problem description

Since the code is correct,  mypy is flagging things wrongly.

#### Expected Output

mypy should accept that `~` operand for Series (as well as the arguments).

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