indentation of FROM and WHERE in longer subquery doesn't match

Much like https://github.com/darold/pgFormatter/issues/240.

SELECT
    SELECT
        sum(amount)
    FROM
        payments + /* keep this comment to avoid crash */ (
            SELECT
                sum(amount)
            FROM payments
            WHERE
                owner_id IN (
                    SELECT
                        id
                    FROM invoices)) + coalesce((
            SELECT
                sum(amount)
            FROM payments
        WHERE
            TYPE IN ('xxx')), 0);

$ pg_format -v
pg_format version 5.0

Start by reproducing the formatting issue with pg_format version 5.0 using the SQL example in the report, then inspect the formatter's handling of nested subqueries and their FROM and WHERE clauses. Done means the longer subquery is consistently indented without the reported mismatch, while preserving the comment and valid SQL output.
