Range type is considered as underlying type when invoking from generic

Sample:
```nim
type
  n16 = range[0'i16..high(int16)]
  SomeObj = ref object

proc doSomethingMore(idOrObj: n16 or SomeObj) =
  discard

proc doSomething(idOrObj: n16 or SomeObj) =
  doSomethingMore(idOrObj) # Error: type mismatch: got (int16)

doSomething(0.n16)
```
