hard_sigmoid operation fails to compile

[taless474]

Using Blaze and Blaze_Tensor heads, Phylanx master and the last stable HPX, I get this error on MSVC:

@taless474 was this resolved?

[taless474]

Yes. This was my bad. When I compared this to #1217 I realized I have saved the wrong commit.

[taless474]

Parsa helped me realize that this problem still persists :/
