Rawi01 db80bb0a21 [fixes #2648] Reset inference context, remove generic information copy
In Java >= 8 ecj uses the inference context to resolve the generic
information. This one is already set before lombok tries rewrite the
method call. Simply copying the information does not cover all the
different cases but reseting the inference contexts and running type
inference again does.
