Fixed issues with removing attribute modifiers

* AttributeModifiersEffect::remove was not calling updateMod with the
  'value' parameter, causing it to have no effect at all for Stackable
  modifiers.

* The cached value of the changed modifier effect was not being
  recalculated when removing modifiers, because it started one layer too
  high (there's an inconsistency here: AttributeModifiersEffect::add
  updates this cached value while AttributeModifiersEffect::remove
  doesn't).
