- 252e1296 doesn't work for all cases as there are code paths
  where a pending launch can be removed from the pending list and not have spent() called.
- There was no reason for iterating the list twice anyway, as all of this takes place with the locks held
- My notifying each one as we process, if there is an Error, we will not leave any stranded. The next run
  through, if there is one, will cover those instances.

... as a control case in the master branch to ensure the changes in the
config-ui-changes do not break its behaviour.

- They have been removed from the pendingLaunches, so once we leave this method we have no reference to them
- Arguably the call to spent should take place when removing from the pendingLaunches, but that would change
  the method contract
