Don't try to run didAbortWorkflow() if the user never provided a command

Browse source 
Summary:
If you type `arc`, you currently get a fatal since $config isn't defined. Don't try to run the hook if we never built a config.

(We could build the config earlier and then run the hook anyway, but $workflow and $command would not be defined. It seems unlikely that executing the hook here is useful, since it affects only the case that the user types `arc` on its own.)

Test Plan: Typed `arc`. Typed `arc diff`, etc.
