remove redundant debug prints

Fixes the function for re-trusting a server.

If you've visited my capsule before using gerbil (gemini.zachdecook.com), then you can test using that; I had to get a new certificate recently.

This also cleans up some printing to aid debugging. (Only potential downside I can imagine is if you liked to have your terminal window side-by-side so you can see ansi escape codes rendered).
