max() and min() give incomplete error message when given invalid type as an argument

Consider the following script:

```
vim -u NONE -i NONE -N --cmd 'echo min(v:true)' --cmd cq
```

. This will show

```
Error detected while processing pre-vimrc command line:
E712: Argument of %s must be a List or Dictionary
0
```

(note `%s`) while it should show “… of min() …” like you will see when using `remove()`. Same for `max()`.
