Merge pull request #532 from hatched/remove-unit-1365177

Fixes issue causing units removed from the inspector to hang around in the ecs.

When we made api calls of the environment but didn't provide a callback it would skip the ecs wrapper callback causing the ecs and db to get out of sync and break the GUI.

Fixes: 
 - #1365177 Removing a unit from the inspector no longer causes the unit to persist in the ecs
 - #1364549 Unable to delete a service with no unplaced units.
Added controls to sort the machine and container tokens.
