UX: When clicking the Create PR button - it writes the prompt in the active tmux session if there are more than one

[genrym]

Version: 1.17.2.

If there are more than one tmux sessions in the task, the Create PR button writes the prompt in the currently active tmux session, and not in the initial one, where the agent is running.

Expected: the prompt to be written in the correct tmux session.
