fix: List e-mail contacts in repl listcontacts command

- After the revisions to support key contacts, the 'listcontacts'
  command in the repl only lists key-contacts.  A separate flag now
  has to be passed to Contact::get_all() to list address contacts.
  This makes it difficult to run the example in README.md because we
  need to see the new contact so we can get its ID for the next
  command in the example, that creates a chat by ID.
- Revised 'listcontacts' command to make a second call to
  Contact::get_all() with the DC_GCL_ADDRESS flag, then print the
  e-mail contacts after the key contacts.
- Revised configuration example in top-level README.md to reflect
  current command output.
