Azat Khuzhin
17b27b6c28 Do not optimize any(arrayJoin()) -> arrayJoin() under optimize_move_functions_out_of_any 
Otherwise the following query will be optimized incorrectly:

    SELECT
        *,
        any(arrayJoin([[], []]))
    FROM numbers(1)
    GROUP BY number

And the result will be:

    ┌─number─┬─arrayJoin(array(array(), array()))─┐
    │      0 │ []                                 │
    │      0 │ []                                 │
    └────────┴────────────────────────────────────┘

While should be:

    ┌─number─┬─any(arrayJoin(array(array(), array())))─┐
    │      0 │ []                                      │
    └────────┴─────────────────────────────────────────┘
