Nlargest on boolean return False first
#### Code Sample, a copy-pastable example if possible

```python
import pandas as pd
pd.Series([True, False]).nlargest(1)
```

> 1    False
> dtype: bool

#### Problem description

If you cast this to any other type, you will have the opposite and expected order.
More generally in python `True > False`. You still have the same order everywhere in pandas.

```python
df = pd.DataFrame({'True': True, 'False': [False] * 2})
df['True'] > df['False']
```

The result is misleading and can easily lead to a debugging process.

#### Expected Output

> 1    True
> dtype: bool

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