Power bat alt issue

[Paopao001]

In some quests like Unyielding Fists: Trial of Bamboo,the player get into a vehicle but got altpower itself.
That is, UnitPower("player", ALTERNATE_POWER_INDEX) returns the value while UnitPower("vehicle", ALTERNATE_POWER_INDEX) returns nil.
But the unit of player frame is vehicle, not player. so the power bar alt don't show up in these cases.

Here's my solution. I wonder if anybody have a better solution.
