[11367]Check SPELL_ATTR_EX == 8 when checking school immunity

[Auntie Mangos]

Is this fix problem with http://getmangos.eu/community/post/132021/#p132021 ?

Rev. 11228

Example: Cyclone has SPELL_ATTR_EX_UNAFFECTED_BY_SCHOOL_IMMUNE so it shouldn't be breakable by spells giving school immunity, such as Divine Shield or Ice Block.

From wowwiki:

Cyclone cannot be broken by abilities such as Divine Shield or Ice Block, but cyclone cannot be cast on players already affected by these types of abilities.

The commit linked below fixes this mechanic.
