  -----

  The issue seems to be that in commit we started using code from
  neutron.tests outside of the testing code. Specifically commit
  7c0f189309789ebcbd5c20c5a86835576ffb5db3 now causes it to get used
  during DB sync. Given that some distribution packages don't package up
  the 'tests' code tree I think we shouldn't be using this code.
