Supplemental fix for issue 14860

`task[] = RTask.init;` has two bugs:

1. `RTask` is a nested struct, so `RTask.init` contains null context pointer.
2. That is a block assignment, so there is a possibility to call
   `RTask.~this()` on garbage objects (stack allocated `buf` is initialized by
`void`).

Fixed to use `emplaceRef` on each elements.
