Using validate on ReferenceInput

[Dreamsorcerer]

What you were expecting:
Setting validate=required() on ReferenceInput to make the label appear as required.

What happened instead:
I needed to set validate on AutocompleteInput instead.

Maybe it would be good to mention validate in the ReferenceInput documentation to avoid this confusion? Unless there's a code fix to ensure that validate gets passed through?

Code I used looks something like:

<ReferenceInput {...props}>
    <AutocompleteInput label={props["label"]} />
</ReferenceInput>

You're right, we should catch the validate prop in <ReferenceInput> and throw an error explaining that it should be set on the child instead. Would you mind opening a PR for that?

This isn't caught by TypeScript as ReferenceInputProps extends InputProps which includes validate. Not sure what the implications are, but should that prop be omitted?
