4.4 RC4.

Convert to lambda does not convert nested lambdas.

Test Case:
	void test() {
		Callable<Runnable> callable= () -> () -> System.out.println();
	}

The ASTRewrite in LambdaExpressionsFix.CreateAnonymousClassCreationOperation#rewriteAST contains both the events to convert both the lambdas to anonymous classes.
However, finally only the outer lambda is converted.

The problem looks similar to bug 434884 comment #2 in the reverse conversion.

Note that if the body of outer lambda is converted to a block, then the cleanup works fine.

This will be fixed with the patch for bug 434884.
