[Spells] Fixes for numhits type 7 counter incrementing incorrectly.

[KayenEQ]

This update addresses an issue where if your using buffs with numhits type 7 which would tic down the hits counter every time a spell was focused, subsequent spell casts or item clicks of unrelated spells would incorrectly tic down that hit counter.

Also this update fixes an issue where focus that apply to dots or hots specifically would not properly tic down the hit counter, was broken in various ways. The correct behavior is that they tic down on initial cast.
