Fix error with using Mind Blast in default priest script.

Fix error with using Mind Blast in default priest script.

- Remove spurious "test" parameter to SpellInfo that shouldn't be there.

- If a condition that returns a number is used as a boolean, then boolean
  evaluation rules dictate that non-zero is true and zero is false.  Fix:

    if SpellCooldown(mind_blast) Spell(mind_blast)

  was probably intended to be:

    if SpellCooldown(mind_blast) == 0 Spell(mind_blast)

  which is simply just:

    Spell(mind_blast)
