Fix for multiple users on the same machine

The issue and fix are described in https://github.com/tmux-plugins/tmux-continuum/issues/16 .

Without this change, tmux-continuum works only for one tmux server on the machine. In a multi-user environment (e.g. a shared server), when multiple users are running their own tmux servers, this means that tmux-continuum works only for one of the users.

This change enables tmux-continuum for one tmux server per user instead of one tmux server per machine.
