Changes lost on file rename

[artgromov]

How to reproduce:

1. Create some drawio.png file
2. Make some changes to created file, notice dot icon on file tab (file not saved).
3. Right click on file in explorer panel (file not autosaved on focus change), select "Rename", type new name, press Enter.
4. File rerenders itself without latest changes =(.

Expected behavior: Same as for txt files: on right click on file in explorer panel should autosave file.
