get-function() not return function type

[Minh-Van]

Hi there,

I got an issue with get-function in sassmeister.com with Sass v3.4.21. It always returns string type instead of function type. This is my code:

@function my-test() { @return null; }
@error type-of(get-function('my-test'));

I have tried google but there're no topic or change log mentions about the change that get-function returns string type.
If its's a bug, I think it's necessary to get a high priority for fix.

get-function() was added in Sass 3.5. I'm not sure why SassMeister hasn't upgraded yet.
