SUMMARY
If you try to rename a file with a very long name, Dolphin shows an error message saying the rename failed. Nevertheless, the name of the file is still updated in the view, and the wrong name persists until the view is refreshed.

STEPS TO REPRODUCE
1. Press F2 to rename a file
2. Paste a very long name (e.g. `Paxton, Smolec, Schwab, Gautschy, Bildsten, Cantiello, Dotter, Farmer, Goldberg, Jermyn, Kanbur, Marchant, Thoul, Townsend, Wolf, Zhang, Timmes 2019 - Modules for Experiments in Stellar Astrophysics (MESA): Pulsating Variable Stars, Rotation, Convective Boundaries, and Energy Conservation.pdf`
3. Press enter
4. Dismiss the error window (that says renaming failed)

OBSERVED RESULTS
Once the error window is dismissed, the file in the view is shown with the new name (even though rename failed). However, refreshing the view (F5) correctly shows the file with the old name.

EXPECTED RESULTS
If renaming a file fails, the file should be shown with the old name even without refreshing the view.
