* Fix mig 141
* Add Migration to fix it
* update null values to false first
* Alter Table if posible
* use dropTableColumns instead of recreateTable
* MySQL use Alter
* Postgres use Alter
* Update models/migrations/v167.go
* Apply suggestions from code review
* use 2x add col & 2x update & 2x drop col
* let sqlite be the only issue
* use recreate since it just WORKS
