Send an empty color code when title is empty but subtitle isn't.

If you have a subtitle and no title, the subtitle never gets sent. This seems to be because there is no text in the title. However if you send an empty color code (such as &r) without any text, the subtitle displays fine. Would it be possible to send empty text so subtitles display when the the string is blank?

connecting-text:
  title: ""
  subtitle: "&aConnecting%dots%"
  actionbar: "&7Connecting you to the server%dots%"
