Improve test data creator
This can be broken down into smaller tickets for individual improvements of the test data creator.
- It would be nice to have not only readily added contacts, but also a bunch of pending contacts.
- Also it would be good if we can make the
briar://-links of both regular and pending contacts available for further interactive testing, for example by printing them on stdout. That would allow for easy testing of contact-readding etc.
- However, testing contacts don't currently have a handshake key from which the briar:// link gets derived. We can generated one, but apparently we need to go through the process of first adding our testing contacts as pending contacts and then making them proper contacts. See this message and the conversation shortly before and after for details: https://chat.briarproject.org/briar/pl/7tcobcx5qfb5mjkto3cj33kw8r
