discovery/gossiper_test: modify TestProcessAnnouncement to process node

Browse Source 
ann last

In this commit, we modify TestProcessAnnouncement to process the node
announcement last. We do this due to the recent change in the gossiper
where we'll only forward node announcements of nodes who intend to
advertised themselves within the network.

This change was needed in order to allow the node announcement to be
broadcast to the greater network, as otherwise the gossiper would assume
the node intends to stay private due to not having any advertised edges.
