Correcting program urls and enhancing call to action:
org urls, program urls, and local urls were getting conflated
programs now have url (coming from openbadger) and localUrl (the CSOL-site url)
program detail pages display an email, program url link, or phone number
  depending on available data
Fix tests: url -> localUrl for programs
