Fix removing parens for in-place objects fix #331

That should cover cases:
```cpp
    f1(:std::vector=(1,2,3));
    f2(:std::vector=(1,2,3),:std::vector=(4,5));
    ar[:index=(1,2)];
    ar2[:index=(1,2), :index=(2,1)];
```
that will generate:
```cpp
    f1(std::vector{1, 2, 3});
    f2(std::vector{1, 2, 3}, std::vector{4, 5});
    cpp2::assert_in_bounds(ar, index{1, 2});
    cpp2::assert_in_bounds(ar2, index{1, 2}, index{2, 1});
```
