Incorrect string builder folding

[aristotll]

int curYear = calendar.get(1);
String date = (new StringBuilder()).append(curYear).append("01").toString();

The result:

Two problems:

1. curYear does not change.
2. toString is redundant.

Thanks.

Hello I've tested this issue in v0.9.9.3 and:

1. ❌ += operator still appears instead of +
2. :white_check_mark: redundant toString seems to be fixed 👍

Thanks for reporting and the pull requests. Should work now with 0.9.9.4.
