Set default value of add another field question to yes in make:publicationType command

Resolves the following code review comment:

Also, when asking if you want another field, I think that "yes" is a better default than "no" because you'll hit yes more times than no (which by definition you'll only hit once)

However, when a terminal is not interactive, it still defaults to no to prevent the program from getting stuck.
