Restructure Almanac tests in uAgents about uagents

[Archento]

Proposal from @ejfitzgerald:

1. Move the current tests into an integration test set and run them periodically. Let's say every day at midnight. The test results for this should be monitored and reported back to the team
2. The test / code should be refactored so that we can isolate the network from the unit test

Proposal from @jrriehl:
We already have Almanac registration tests running every hour or so on our continuous testing service, so I'd say it's safe to drop these tests. Ideally, I would suggest that we update these tests to simulate or mock the txs for validation purposes.
