Fix Camille's passive

The passive has weird interactions with many champions. The passive is based on which type (magic or physical) would mitigate the most damage from her target's damage. A example is, a tank has a Sunfire Cape and the tank for, sometimes the tank will be considered a magic damage target since they are doing damage with the Sunfire Cape's passive. This problem is really annoying because trying to trade autos with a tank and having them be considered magic damage makes you take increased damage and basically makes your passive useless for the most part.
