Title: Normalize `decl.before` and `decl.between`

`decl.before` and `decl.between` can be `undefined`.

Also can be `undefined` following properties:

- `comment.before`
- `decl.important`
- `rule.before`
- `rule.between`
- `rule.semicolon`
- `rule.after`
- `atRule.before`
- `atRule.afterName`
- `atRule.between`
- `atRule.semicolon`
- `atRule.after`

But these properties reset correctly.
