songsview: fix a TypeError
Just a small fix to prevent a TypeError when displacing a row in selection mode in SongsView.
Here's the resolved error:
Traceback (most recent call last):
File "/app/lib/python3.7/site-packages/gnomemusic/views/songsview.py", line 200, in _on_view_clicked
path, col, cell_x, cell_y = self._view.get_path_at_pos(x, y)
TypeError: cannot unpack non-iterable NoneType object
L’application s’est fermée
