After the editor for a downloaded file is closed, the file is deleted from disk. I don't think the issue used to happen on 3.6

Steps to Reproduce:
1. Install a debug app on the phone
2. Make the app write something to internal storage (for example with `context.openFileOutput("file.txt", 0)`)
3. Connect the phone to the computer via adb
4. Use "Device File Explorer" (bottom right) and navigate to `/data/data/<application id>/files/file.txt`
5. Double click on the file to download it and open it in the IDE
6. Without doing any modifications, close the editor.
7. Navigate to the file in finder `/Users/<user>/Documents/AndroidStudio/DeviceExplorer/<device id>/data/data/<application id>/files/file.txt` and notice that it no longer exists.
