Migrate all database tests from gopkg.in/check.v1 Suite-based testing
to standard Go tests with testify assert/require.
Changes:
- Remove empty Suite files (hscontrol/suite_test.go, hscontrol/mapper/suite_test.go)
- Convert hscontrol/db/suite_test.go to modern helpers only
- Convert 6 Suite test methods in node_test.go to standalone tests
- Convert 5 Suite test methods in api_key_test.go to standalone tests
- Fix stale global variable reference in db_test.go
The legacy TestListPeers Suite method was renamed to TestListPeersManyNodes
to avoid conflict with the existing modern TestListPeers function, as they
test different aspects (basic peer listing vs ID filtering).
This commit replaces the timestamp based state system with a new
one that has update channels directly to the connected nodes. It
will send an update to all listening clients via the polling
mechanism.
It introduces a new package notifier, which has a concurrency safe
manager for all our channels to the connected nodes.
