#require queries are incompatible with MaxScoreDocumentModel

Example query:

#require( #all( snord116 ) #combine:0=1.0(#sdm(snord116)) )

Exception in thread "main" java.lang.IllegalArgumentException: Query tree does not support delta scoring interface.
#require(
    #all(
        #counts:snord116:part=postings.krovetz()
      )
    #combine:0=1.0:norm=false(
        #dirichlet:avgLength=1590.3536612757132:collectionLength=6060958670:documentCount=3811076:maximumCount=143:mu=2500.0:nodeFrequency=151(
            #lengths:document:part=lengths()
            #counts:snord116:part=postings.krovetz()
          )
      )
  )

When I set parameter "deltaReady" to false, it runs without problems.

    // if the node is deltaCapable
    if (isDeltaCapable(original)) {
      // ensure the correct processing model can be used
      qp.set("deltaReady", true);

      // now add w parameters to each node
      propagateWeights(original, qp);
    }

    return original;

Filter nodes should cause deltaReady to be set to false (missing else case)
