Title:
  instance.delete notification is missing for unscheduled instance

Status in OpenStack Compute (nova):
  Confirmed
Status in OpenStack Compute (nova) ocata series:
  New

Bug description:
  Description
  ===========
  It seems that the Move instance creation to conductor commit [1] changed when and how the instance.delete notification is emitted for an unscheduled instance. Unfortunately the legacy notification doesn't have test coverage and the versioned notification coverage are still on review [2] for this case.

  Before [1] the instance.delete for an unscheduled instance is emitted from here [3]. But after [1] the execution of the same delete operation goes to a new direction [4] and never reaches [3].
  Before [1] the new test coverage in [2] was passing but now after [1] is merged the test_create_server_error fails as the instance.delete notification is not emitted.

  Steps to reproduce
  ==================

  Run the nova functional test in patch [2] before and after commit [1].
  The test_create_server_error will pass before and fail after commit
  [1] due to missing instance.delete notification.

  
  Environment
  ===========

  Nova functional test env with based on commit
