`Coder: View Logs` can show the wrong log file

[code-asher]

We look for the SSH PID then store that, but if there is a reconnection we could get a new SSH process and now we are pointing to the wrong log file.

Also, if you are not currently connected the command gives you nothing. Maybe we should open the directory in that case and show a file picker ordered by recency? Or just always open the most recent one? That would also solve the above case.
