In this commit, we unify how all unit tests that make use of the graph create their test ChannelGraph instance. This will make it easier to ensure that once we plug in different graph DB implementations, that all unit tests are run against all variants of the graph DB. With this commit, `NewChannelGraph` is mainly only called via `MakeTestGraph` for all tests _except_ for `TestGraphLoading` which needs to be able to reload a ChannelGraph with the same backend. This will be addressed in a follow-up commit once more helpers are defined. Note that in all previous packages where we created a test graph using `kvdb.GetBoltBackend`, we now need to add a `TestMain` function with a call to `kvdb.RunTest` since the `MakeTestGraph` helper uses `GetTestBackend` instead of `kvdb.GetBoltBackend` which requires an embedded postgres instance to be running.
routing
The routing package implements authentication+validation of channel announcements, pruning of the channel graph, path finding within the network, sending outgoing payments into the network and synchronizing new peers to our channel graph state.
