Null check can be replaced with method call

Reports null checks that can be replaced with a call to a static method from Objects or Stream.

Example:

if (message == null) {
  application.messageStorage().save(new EmptyMessage());
} else {
  application.messageStorage().save(message);
}

After the quick-fix is applied:

application.messageStorage()
  .save(Objects.requireNonNullElseGet(message, () -> new EmptyMessage()));

Use the Don't warn if the replacement is longer than the original option to ignore the cases when the replacement is longer than the original code.
