Drop the nautilus-sendto menu entry
Context here:
https://mail.gnome.org/archives/desktop-devel-list/2019-February/msg00057.html
Current implementation does not work in sandbox environment. And No directly replacement in GTK since the mailto: URI standard does not support attachment.
I think we can drop this feature as we drop the recent view. Since this feature should be implemented by system file manager (Nautilus in GNOME) and we already support opening the containing folder in the menu.
And we can replace the menu entry with presentation mode.
