BUG: continuation of updateMethods with empty activeDesignVariables

When activeDesignVariables are not set explicitly, all design variables
are treated as active. These were allocated properly when starting from
0 but not when starting from an intermediate optimisation cycle
(e.g. running 5 optimisation cycles, stopping and restarting).

TUT: added a new tutorial including the restart of an optimisation run
to help identify future regression
