* Add smoke tests for folding ranges * fix index out of bounds in foldingRanges closes #801 For invalid syntax trees, zig's parser seems to return bogus data where startToken > endToken, which then causes everything else to crash. This seems like a deeper issue, which needs to be fixed "properly", but let's just paper over it here.
