> Closely related to ARROW-13117 is the problem of {{type()}} and {{type_id()}} 
> not working for scalar expressions. For example, currently this happens:
> {code:r}> Expression$scalar("foo")$type()
> Error: !is.null(schema) is not TRUE
> > Expression$scalar(42L)$type()
> Error: !is.null(schema) is not TRUE{code}
> This is what we want to happen:
> {code:r}> Expression$scalar("foo")$type()
> Utf8
> string
> > Expression$scalar(42L)$type()
> Int32
> int32{code}
> This is simple to solve; we just need to set {{schema}} to an empty schema 
> for all scalar expressions.
