    libcryptui: fix logic flaw in the prompt recipients dialog
    
    The prompt recipients dialog has been broken in commit
    
https://github.com/GNOME/libcryptui/commit/cd74aa6bf810a5ce0935d2ec89d6db64dbbde24d#diff-f0ea8a1eef5386b0149314d2a1743e85L202
    
    The patch fixes the logic there and makes seahorse-tool's
    encrypt command work again. Therefore, seahorse plugins for both
    Nautilus and Nemo should start working as well.
