"MM0000: Unexpected error" when an invalid character is used in the Assembly Name: "Hello, Mac"

### Steps to Reproduce

1. Attempt to follow https://docs.microsoft.com/en-us/xamarin/mac/get-started/hello-mac
2. Try to build the resulting project.

### Expected Behavior

The app builds without any errors and then running the app works as well.

### Actual Behavior

Building the app fails with:

```
/Users/barend/Developer/CSharp/HelloMac/MMP: Error MM0000: Unexpected error - Please file a bug report at http://bugzilla.xamarin.com (MM0000) (HelloMac)
```

I found https://bugzilla.xamarin.com/show_bug.cgi?id=44697, which says:

> That exception means we crashed inside mmp, which is never acceptable. With more information, we can get to the bottom of this.
