[iOS 9.0.x] Icons not appearing on lock screen and disappearing when changing apps

[fritz-fritz]

I've noticed a few bugs/problems since iOS 9.0.x:

• The master branch does not have the latest code pushed to it
  • An update came out through the repo but there is no update here.
  • This hurts developers from investigating what the problem is and trying to fix it.
• Icons do not appear on lock screen
  • Seems to affect all graphic icons (versus custom text)
  • Once the entire status bar was gone
• Icons sometimes disappear when switching apps
  • Seems to affect any non-standard icons or custom text
• Enabling Protean sometimes prevents other icons from appearing
  • Seems like it is an issue with Protean and not libstatusbar but mentioning for good measure

I noticed there were comments in the open pull request regarding some of these issues. I decided to open the issue to provide a better place to discuss.
