Fix: Add extra checks when lambda/method ref is converted to intersection type

A lambda/methdod reference can be converted to an intersection type provided that:

*) All types in the intersection are interface types
*) The first type of the intersection is a functional interface
*) The additional bounds of the intersection are marker interfaces
