Match policies malfunctioning on rabbit-like graph

[jameshcorbett]

Using the match policies low and lownode on this JGF representation of rzvernal: rzvernal_R_norabbit.json

and the following jobspec:

version: 9999
resources:
    - type: slot
      count: 4
      label: default
      with:
      - type: ssd
        count: 1
      - type: node
        count: 1
        with:
        - type: core
          count: 1
# a comment
attributes:
  system:
    duration: 3600
tasks:
  - command: [ "app" ]
    slot: default
    count:
      per_slot: 1

resource-query will allocate far too many resources:
