IFluidContainer.attach() test

[vladsud]

This PR shows issue with IFluidContainer.attach signature. It should fail compilation, but it does not. It demonstrates that users have no clue what is allowed / supported in this flow. There is no way to find it (other than parsing code), and no way to enforce contract.
