Update the query for the "Recently closed" dashboard section to exclude
WIP changes and changes ignored by the viewing user.
We need integration with a Gerrit server and a search index to properly
test these queries, so I've added tests for these queries to
AbstractQueryChangesTest.java. This ensures that every search index
implementation maintains expected behavior (and that we defined the queries
correctly).
