black-oil: fix some stupid errors with vaporized oil

Browse Source 
obviously if the switching variable is interpreted as x_g^O, the gas
phase is present, because in this case it is the only phase. Also,
when the oil phase appears, the gas saturation is 1-Sw, not 1. (the
last issue only happened in the vaporized case because the switch
variable would never get the meaning of "oil component's mole fraction
in the gas phase".)
