Review Comment:
`Symbol("foo bar").int` previously just passed `"foo bar"` to the
`AttributeReference` without parsing an `UnresolvedAttribute`. We now call
`attr()` which _is_ parsing `"foo bar"` and that fails without backticks.
Alternatively, we can `quoteIfNeeded` in `DslSymbol` and treat, e.g.,
`Symbol("foo.bar")` as single-part (which is the current behaviour). But I
think it's confusing if `$"foo.bar"` returns a multi-part attribute and
`Symbol("foo.bar")` doesn't.

So I rather just update the test.
