Save grouped sessions

Browse Source 
Grouped sessions are session started with the command
`tmux new-session -t <existing-session-name>`

Those sessions share the panes and windows with the existing, original
session.
We're making sure to identify and save grouped sessions.
On the other hand, we don't want to save panes and windows twice
