[gui] "Save Mappings" doesn't save all of them.

[ReDJstone]

Issue details

When i Save Mappings, some do not save into the text file.
(No type of file works. I tried. Though I'm using recaf simple to be able to see the text easily.)

But if i do not close the app, i can Save Mappings, then Close Mappings and Open Mappings using the same file, and every single mapping is exactly as i left it.
This feels strange, because as i said, some mappings that reappear when i open the mappings file are not saved there at all!

But the real problem comes when closing the app.
The next time i open it, i try to Open Mappings and now it loads only the ones that are in the text file. The ones that are not in there, are lost.

When changing the name of some variables, i get exceptions on the console.

@ReDJstone it will be very helpful if you share APK file (or link to it) and full name of node which not saving in mappings file after rename. With that info, it will be easier to reproduce this issue 🙂

[ReDJstone]

Nevermind.
When i tried to save mappings it threw a lot of exceptions and saved an empty file over the mappings file that i had created. I just lost all my mappings.
