bug: fix core dump if the terminal is closed while bottom is open (#1230)

* bug: fix core dump if the terminal is closed

The cause was:

- bottom thinks it's panicking if the terminal is closed.
- The panic hook tried to print out to the terminal - but the terminal
  was closed! It would unwrap and thus panic even harder.
- To solve this, we just make the panic hook calls not unwrap, since
  honestly if they fail it's whatever as far as I understand it.
