append_env_path always triggered a state change

[cywjackson]

i love the append_env_path feature , because it allows us no need to handle PATH via other obscure ways.
but using this feature always trigger the state change of the resource, because it always got executed. That's not good because we also like to use the notification feature on ark to notify the service that should be restarted (on change).

but we can't always be restarting the service especially when there is no change. this property should only be triggered the action when there is a change.

Couldn't you just have an if condition after the property checking if the binary is already in the path? I think we could probably make that better but this should be solvable in your wrapper cookbook.
