Fixing case when an invokeable object is used as a callback

[burzum]

Obviously nobody else had yet the desire to move the sometimes pretty long callbacks into proper objects. Well, we did and figured out the plugin doesn't like it. 😃 This fixes the problem.

The path processor is configurable, so for such cases you can use a custom path process class and override it's filename() method. It would be the same effort and making your own invokable class.

You should be able to use invokable class instance as callback without issues with the 5.0.0-RC2 release.
