Azat Khuzhin 8b438bcd3c Change formatting of subqueries (make it more human friendly)
Fix trailing whitespaces in FROM/IN clause with subqueries in multiline
mode, and also changes the output of the queries slightly in a more
human friendly way.

Before:

    $ clickhouse-format <<<'select * from system.one, (select * from system.one)'
    SELECT *
    FROM system.one
    ,
    (
        SELECT *
        FROM system.one
    )

After:

    $ clickhouse-format <<<'select * from system.one, (select * from system.one)'
    SELECT *
    FROM system.one,
    (
        SELECT *
        FROM system.one
    )

v2: Fix subqueries formatting in a different way
v3: Adjust *.reference in tests
v4: Fix modernize-loop-convert in ASTTablesInSelectQuery
