Bug in displaying user profile - PIN number (from "imamopravoznati-theme-0.39.1.6" branch)

[schlos]

Describe the bug

It seems that Alaveteli expected PIN number to be a Date, but I can't see any validation, and db migration has set field into string. Requirement that was being tested is:

• Customize request email - add postal address and PIN (OIB) #12

An ActionView::Template::Error occurred in user#show:

  Object must be a Date, DateTime or Time object. "12345678901" given.
