[FLOW3-general] Introduce Method WITH parameters via AOP Advice and Interface

[Andreas Förthner]

Hi Torsten,

this is a known bug. There is already a change in gerrit, that should fix
the issue: https://review.typo3.org/#change,5395

Can you try it and maybe add your vote to the change? That would be great!
