cryptogopher 3788f1a749 Fix db:seed:export task
* replace variable names with Hash to avoid invalid Ruby identifiers
* export all values as single-quoted to avoid string interpolation and
  treating BigDecimal numbers as Float
* #truncate table instead of #delete_all to avoid foreing_key
  constraints errors
