topic: add more branchcache entries to test-topic-flow-publish-flag.t It seems these new entries started appearing after the recent-ish refactoring of branchcache in core. Now the server and the client have the same branch cache data on disk, which is probably for the best. The actual output with changeset hashes is: branch2-base:c0155e8ec55a9b46d415d5b13a319d0c80e26e9d o double//slash branch2-immutable:c0155e8ec55a9b46d415d5b13a319d0c80e26e9d o double//slash branch2-served:256a2cb64fd8ada4ff18d57606d212f094cb50fb o double//slash c0155e8ec55a is public, so it's correct to be in "base" and "immutable" repo views. 256a2cb64fd8 is draft (without topic), so it's expected to be in the "served" view.
