    Deal with lingering callbacks in the eds/set-avatar test.
    
    These can be called after we've set this._main_loop = null,
    so if we don't check it first, we'll hit warnings (which get
    treated as errors).
    
    This isn't an ideal solution, but there doesn't seem to be a
    great way to avoid the handlers from firing after we no
    longer care (we need something like thaw/freeze_notify(),
    except for general signals, not just notify).
