Describe the bug
If you give I18n::translateCount() a translation key that only has a single value, it will not replace {{ count }} with the passed value.
For a language like Chinese, there isn't a concept of a "plural form" that varies because of the number. So it's 0 天, 1 天, 2 天, 3 天, etc.
That makes creating translation strings for a language lie Chinese unnecessarily verbose by listing the same string 3 times.
