Changing screen orientation discards checklist input

[familycrest]

I love your app "Notes" for Android. I've been using it for years, so thanks.

Bug: When adding items to a checklist, if the screen orientation is changed from either orientation the input box will disappear and the new items will not be added to the checklist.

Steps to reproduce:

1. Open a new or existing checklist. 2. Click the plus button to add an item to the checklist, but do not press "OK". The screen orientation you start in does not matter. 3. Rotate the screen to change the screen orientation Make sure your screen isn't locked, of course. 4. The input box should disappear, as well as anything you input.

Why this is an issue:

In the past I've put in large amounts of input only to have it all disappear when I accidentally rotate my phone. I'm sure others have had that happen. This has actually been a bug for years, but I didn't think to report it until now.
