Selected evidence resets to 0 while keeping desc when theme is reloaded

[Crystalwarrior]

Describe the bug
Reloading the theme causes the selected evidence to reset to 0, however the description etc. are still kept. This results in overwriting the 0th evidence with whatever evidence you were editing prior to theme reload. Especially annoying with subthemes switching.

To reproduce
Steps to reproduce the behavior:

1. Open Evidence tab in KFO 2x Widescreen variant (any theme that doesn't overlay desc over evidence works)
2. Select 5th evidence
3. Start editing it
4. Press "Reload Theme"
5. Press "Save"
6. Your 0th evidence is now a copy of 5th

Expected behavior
Reloading the theme does not affect your selected evidence (it's kept the same regardless)
