Change in Let's encrypt response broke client if contact is set #299
Description
As mentioned here, Let's Encrypt no longer includes contact information in its responses: https://community.letsencrypt.org/t/did-you-change-the-response-of-new-account/238188
That breaks acme-tiny if contact information is requested:
Traceback (most recent call last):
File "/home/user/bin/acme_tiny.py", line 199, in <module>
main(sys.argv[1:])
File "/home/user/bin/acme_tiny.py", line 195, in main

log.info("Updated contact details:\n{0}".format("\n".join(account['contact'])))

KeyError: 'contact'
Failed retrieving cert
Workaround: Don't use the --contact command line option.
