[Client] Disable automatic transition to other chargen menus from OpenMW

Previously, after finishing the TES3MP chargen once, mCreationStage was set to 4 in OpenMW, which in turn made it impossible to go through only specific chargen menus again as the result of the relevant TES3MP script function (tes3mp.SetCharGenStage(pid, startStage, endStage) in 0.6.3, player:setCharGenStages(startStage, endStage) in 0.7). In other words, trying to allow a player to just choose their class again made it so the player started at that menu and went through all the other subsequent menus as well, i.e. the player went through the class, birthsign and review menus.
