Panic in sesh/tmux/list.go running sesh list -t

Thanks for the hard work on this package!

I'm trying to configure my dev environment with multiple tmux sessions orchestrated using tmuxinator. I've simplified the environment to 2 sessions to illustrate the issue. Running sesh list -t panics with an NPE.

As far as I can tell, tmuxinator isn't doing anything particularly out of the ordinary when creating a session https://github.com/search?q=repo:tmuxinator/tmuxinator%20new-session&type=code.

Here's a text version of the stack trace

❯ sesh list -t
