fix: incomplete generated code for pk

[jjangga0214]

As we can see, part of using primary key is missing.

Never mind. I missed specifying pk from diesel::table!

But I still think it'd be good to print out "[ERROR] You're missing primary key!" from CLI output.

could you provide a example diesel table that produces this problem?
