fix for panic, minor asthetics

The cause of the panic was that the UserDetail table was never created in the DB.
I also removed a bunch of `autofucus` from the form. It was causing the page to focus on the last one, which was at the bottom of the page.

The next thing we should do is:
- move the DB user fill data to the `user` module  
   ( `sample/app/controllers/db.go` -> `modules/user/user_tables.go`)
- add more data for the user DB fill
