default_configuration raises errors when running migrations on clean database

[defkode]

sample error:

SQLite3::SQLException: no such table: config: SELECT * FROM "config" WHERE ("config"."associated_id" IS NULL AND "config"."associated_type" = 'User' AND "config"."key" = 'favourite_color') LIMIT 1

it tries to make a query to config table, when no table was set yet

try: rake db:drop, rake db:migrate
