    password-manager: Fix crash when deleting all passwords
    
    This broke in 7d080a31. The callback here is not prepared for there to
    be no async data, but the async data is only required when clearing a
    single password, not when clearing all of them. The GTask is optional
    even if there is async data. We're just going to need a bunch of
    conditionals here.
    
    Fixes #1773
