Fix a crash when a colon line is marked between # fmt: off and # fmt: on #3439

Description

Fixes #3436.

Note that the # fmt: on line is always normalized to the next statement so its indentation is moved in this case. This isn't ideal, but at least it shouldn't crash.

Checklist - did you ...

I feel like we should write developer docs on how fmt: off/on/skip work. The logic is already complicated as-is and the edge cases are incredibly confusing sometimes...

Also technically this is invalid use of # fmt: off/on but this is just a limitation of Black since there's no way to represent a # fmt: on at the right indent level right between indention levels.
