    web-extension: Fix D-Bus connection after autoptr conversion
    
    Code changes are dangerous. In 8e1c71ff50d185c11d7f047427c27048c9fcdfa5
    I messed up and caused the web extension's GDBusConnection to be
    immediately destroyed after successfully connecting to the UI process.
    Oops. I discovered this so quickly only by chance, because I happened to
    be debugging a password manager issue.
