"Implement missing members" bad placements in braceless syntax

[Lucas Nouguier]

Describe the bug

When using the quick-fix "implement missing members" in braceless syntax it inserts the dummy implementation at the wrong place:

• sometimes in the middle of a def
• sometimes it adds a body like

case class ... extends ...:
  def foo = "foo" {
    override def ...
  }
