Exception Raised for Static Rank Tensor inside the Tensor Times Tensor Product

This exception is raised because the static rank extents for result type are not filled with one but instead default initialized to zero, making the extents invalid.

```cpp
auto A = tensor_static_rank(4,3);
auto B = tensor_static_rank(3,4,2);
auto AB = A(_d,_f) * B(_f,_d,_); // Throws the exception
```
