check pawn entity health

[BestAwperEver]

It looks like in the past 12 hours almost every cs2 demo from Faceit (maybe even every single one, I'm not sure about that) crashes with panic: interface conversion: interface {} is nil, not uint64 because of Any field of the m_iPawnHealth property of any player controller entity always being nil, so I'm proposing this as a hotfix.

Thank you!
Armor is also affected, could you please change it to return getInt(p.PlayerPawnEntity(), "m_ArmorValue")?

My bad, it has been changed recently in #438

Thanks
