Bugfix. Using diet templates in routes declareted in *RouteFunction*

Example code:

```d
module routes.blog;

import cmsed.base;

class Home : OORoute {
    @RouteFunction(RouteType.Get, "/test/", "index")
    bool test() {return true;}
}
```

If template was declarated in such way program was not compiled.

Now bug seems to be fixed, but may be there are better way to fix it.
