Part of bzrlib.tests.per_workingtree
These tests are in addition to the tests from per_tree.test_revision_tree which cover the behaviour expected from all Trees. WorkingTrees implement the revision_tree api to allow access to cached data, but we don't require that all WorkingTrees have such a cache, so these tests are testing that when there is a cache, it performs correctly.
