Align of mutl_way_if incorrect

In my `.stylish-haskell.yaml` I have:
```
# Never align the right hand side of some elements.
- simple_align:
cases: never
top_level_patterns: never
records: never
multi_way_if: never
- squash: {}
```
and after using `stylish-haskell` on one of my files, I get the following as part of the diff:
```
st <- getFileStatus fp
if
| isRegularFile st -> pure (fp : files, dirs)
- | isDirectory st -> pure (files, fp : dirs)
- | otherwise -> pure (files, dirs)
+ | isDirectory st -> pure (files, fp : dirs)
+ | otherwise -> pure (files, dirs)
```
Using version `0.14.6.0`.

Reproduce the report with the shown .stylish-haskell.yaml configuration and a multi-way if containing the displayed guards, using stylish-haskell 0.14.6.0 as the baseline. Trace the simple_align handling for multi_way_if and verify that setting it to never leaves the right-hand sides unaligned; no source file or test is named in the issue.
