Seeding the DB creates duplicate roles.

[Jason Dugdale]

I came across this by installing the app, and following the tutorial. I hit rake db:reset, followed by rake db:migrate then rake db:seed. When the DB is reset, the example users are added to the DB by default, so seeding the DB creates these roles again:

sqlite> select * from roles;

I ran into this too and had to manually delete roles. Could we solve this by using the find_or_create_by_name helper method when creating development roles?

Thanks @dugjason for reporting the issue and thanks @stevecastaneda for the helpful suggestion. It's great to see a solution offered before I even address the issue.
