Fix for shield current and max incorrectly displaying

Line 404 and 405 is removed in newer versions of unitframes. (development)
It's not in the VikingUnitFrames development branch file so I'm not sure why it doens't light up as adding it? 
@itsthatguy I'm missing some understanding of github here. 
This line is not present in the current development branch of UnitFrames. This pull does however show it, it's just not showing if it adds it?
Would I be safe to assume that these lines won't get added when accepting the pull?
