Make objc-related expectations compile

Fixes #1004.

After looking at how `msg_send!` is supposed to be used, I realized that
we were erroneously passing type signatures to it.

The expectations compile now, but some of them are not formatted properly.
My guess is that `rustfmt` does not know how to format the following:

```
msg_send!(obj, arg1:1 arg2:2 arg3:3)
```

Notice the lack of separatros between the `arg`s.

Any advice on how to proceed here is appreciated.
