plusLayer has wrong position when using with bottom bar

[rbresjer]

Steps to reproduce

1. Create a UITabBarController with two child UIViewControllers
2. Add a Floaty with an item to the first child UIVIewControllers
3. Run the app
4. Open/expand the Floaty
5. Switch to the other UIVIewController
6. Switch back to the UIVIewController with the Floaty

Expected behaviour

The Floaty looks normal, like it looked before you switched tabs.

Actual behaviour

The X-button (plusLayer) is offset incorrectly:

Workaround

Close the Floaty on viewWillDisappear, e.g.:

override func viewWillDisappear(_ animated: Bool) {
  floaty.close()
  super.viewWillDisappear(animated)
}

4.1.0 has the same issue, so I don't think this is related to #250.
