    Avoid repeating the self encryption key in cryptui_key_chooser_get_recipients()
    
    When using self encryption, cryptui_key_chooser_get_recipients() would
    previously always prepend the key to the recipient list. This is uneeded
    if the key is already in there.
    
    This change makes prompt_recipients() in seahorse-tool.c happier when
    selecting the key using for signing in the recipient list.
