Member of a @defined elements is also generated

[carueda]

Describe the bug

A member of a @defined element is also generated (as if not using the annotation), but it should not.

To Reproduce

Use this input config schema:

#@define
Shared {
  c: string
  d: int
}

example {
  a: Shared
}

This will generate:

Java:

public final JavaIssue125aCfg.Shared Shared;

Scala:

Shared  : ScalaIssue125aCfg.Shared,

Expected behavior

As documented, the @define annotation by itself should only generate the corresponding type (a class in the above example) in the target language.

Target language(s):

• Java
• Scala

Additional context
Although not really surprising (due to the WiP status for a full shared object definition support), this was really exposed while looking into #125 .

EDIT: Actually, this used to work as intended AFAICR so this looks like a regression.

Added related tests but, weird, I was not actually able to reproduce.
