extension migration rollback fails

[javinto]

When I run a db:rollback to rollback migrations generated by an extension it fails with the exception

wrong number of arguments (given 1, expected 0)

triggered by the following code ::Refinery::Page.delete_all({:link_url => "/my_extension"})

This should be: ::Refinery::Page.where({:link_url => "/my_extension"}).delete_all

The same goes for the .destroy_all command.
