Description:
Fix small issue with exposed rendering

If a service was already exposed when the GUI started, trying to
unexpose it would not change the visual representation. This was
because we were rendering multiple instances of the exposed icon per
service block, unnecessarily, and not always removing all of the ones we
needed to. Now we simply only add a single exposed icon at a time.

I plan to self-review.
