JVM: fix EnclosingMethod information for SAMs in inline lambdas

Pass parentContext to SamWrapperCodegen from the outside instead of
using the one from parentCodegen. The difference is that in case of an
inline lambda, we're creating an InlineLambdaContext whose parent is a
ClosureContext, but the codegen for that lambda has that latter
ClosureContext as its context. So the getNonInlineOuterContext call in
SamWrapperCodegen.generateInnerClassInformation wasn't able to identify
that this is a context of a lambda that needs to be skipped, and
generated it as EnclosingMethod, which caused Java reflection to fail
because once that lambda was inlined, it was removed and thus didn't
make it to runtime.
