[6947] Fixed learning some spells triggred by learning another spell.

At prepering learning spell dependences at server load mark
as auto-learned spells from DBC data only leraned
from telents/passive/skill-setting spells.
Expected "regression": if player learn "learning spell" then
he will always auto-learn spell learned by this "learning spell" also.
