JetBrains: Get rid of IntelliJ warnings
Created by: vdavid
The warnings bothered me because I like it when everything that's yellow or red is something that we should actually get rid of. There is still the AppUIExecutor.onUiThread().execute() call (here) that I haven't been able to fix, but all other non-generated files are warning-free now in the jetbrains folder.
Test plan
Run the code and make sure it runs as intended. I went through the main functionality and it seems to work: https://www.loom.com/share/efcfaae8b1844c87ab29e86c114ad4e2
