Fix activation of initial context

This broke with 40f6767; the symptom is that starting lazygit with a git
arg (e.g. "lazygit log") wouldn't activate the requested panel correctly. While
it would show in the expanded view, it didn't have a green frame, and keyboard
events would go to the files panel.
