auto merge of #12065 : mrshu/rust/error-formating-fix, r=alexcrichton

This pull request tries to fix #12050.

I went after these wrong errors quite aggressively so it might be that I also changed some strings that are not actual errors.

Please point those out and I will update this pull request accordingly.
