Bug Fix getting Class Info from a class with a field from another class' inner class.

[nbauernfeind]

I'm using jackson-module-scala which uses scalabeans under the covers. I want to serialize a class that looks like this:

class Metrics {
  outer =>
  val numThingA = new Counter(...)
  val numThingB  = new Counter(...)
  val currThingC = new AtomicReference(...)
  // ... etc you get the point

  def newSnapshot = new Snapshot  
  case class Snapshot (
    numThingA: Long = outer.numThingA.count,
    numThingB: Long = outer.numThingB.count,
    currThingC: C = outer.currThingC.get
  )
}

In the end I stick the snapshot into a case class:

case class DataResponse(..., metrics: Metrics#Snapshot)

But it fails to serialize the snapshot with this exception:

scala.MatchError: org.scalastuff.scalabeans.sig.OuterTestClass (of class org.scalastuff.scalabeans.sig.ClassDeclExtractor$$anonfun$13$$anon$10)

So, here's a fix... and it works. Test fails beforehand but required the helper classes to be at the top level.
