Try statements have a body: Fix formatter instability (#5558)

## Summary

The following code was previously leading to unstable formatting:
```python
try:
    try:
        pass
    finally:
        print(1)  # issue7208
except A:
    pass
```
The comment would be formatted as a trailing comment of `try` which is
unstable as an end-of-line comment gets two extra whitespaces.

This was originally found in
99b00efd5e/Lib/getpass.py (L68-L91)

## Test Plan

I added a regression test
