bug: contains selector does not work as expected when how=all

[af6140]

What happened?

The contains selector works as any even specified how=all

t2 = ibis.table(
    dict(a="int64", b="string", c="float", d="array<int16>", ab="struct<x: int>", abc="int64")
)

exprt = t2.select(s.contains(("a", "b"),how=all))
expr.columns

It will show columns of "a" and "b" other than "ab" and "abc"

What version of ibis are you using?

11.0.0

What backend(s) are you using, if any?

No response

Relevant log output

('a', 'b')
