Remove uncommitted units when the ghost service is removed.
Merge pull request #435 from jaycee/clear-unplaced-unit

Remove uncommitted units when the ghost service is removed.

`_destroyQueuedService` attempts to remove all the items associated with the queued ("ghost") service. While it gets the entries for adding the uncommitted units, it doesn't remove the actual units.

This branch remedies that, and updates the test showing it removes queued service to demonstrate it also removes uncommited units.
Disallow deleting the 'root container' token.
Adding manually placed units calls env add_unit method
Created addGhostAndEcsUnits method in utils to add ghost units which can be placed in the machine view.

auto placing units via the inspectors new scale-up UI now creates machines, creates units, and places the units on the machines
Wrote tests for the utils addGhostAndEcsUnits method
Clean up uses of forEach
Fix and add additional tests.
Added tests for the inspector scale-up UI communicating with the back end
