Move restoring pre pull options to initialising of c2 context

Move restoring pre pull options to initialising of c2 context

We currently delay restoring these options until we actually must
restore them. Since there is no reason to do so apart from the very
minor saving to not have to execute that code when a connection fails,
move them it into the general context_2 initialisation.

Patch V2: rebase on master.
