normal action plugin: remove superfluous code (#79690)

* Remove obsolete 'if'

The result dict returned by super.run() will never have a 'skipped' entry.
Without the if, it is more clear that wrap_async is actually defined at the end of the function.

* Remove more dead code.

The result dict will also not contain invocation.

* Remove notes.
