Bug: Text-image pairs are becoming scrambled.

[UrzasLegacy]

- Sometimes when usingdelete pair, the contents of the text box seem to automatically get saved to that index. For example: I delete index 4 and now index 5 has the text saved to it instead.

I'm not 100% sure if this is what happened with me, but I noticed at some point that some of my text image pairs were swapped. Very painful bug to rectify!

I love your app, so I wanted to see if I could bang this one out. I noticed in your Todo section you are already aware of the issue :P Have you made any headway?

Edit: After looking at it a bit, would setting save to False on these two calls to update_pair fix the issue?

self.update_pair("prev")

self.update_pair("prev")

Added these changes to my PR for review.

I'm sorry you had to deal with the app messing with your captions. It's something that should have been fixed earlier.

I seriously appreciate that you've looked into this yourself, your changes appear to have fixed the issue, and I've merged your pull request. #30
