Make missing auto-call arguments throw an eval error

The PR #4240 changed messag of the error that was thrown when an auto-called function was missing an argument. However this change also changed the type of the error, from `EvalError` to a new `MissingArgumentError`. This broke hydra which was relying on an `EvalError` being thrown. Make `MissingArgumentError` a subclass of `EvalError` to un-break hydra.
