X.A.TopicSpace: More aggressively use X.H.WorkspaceHistory
X.A.TopicSpace: More aggressively use X.H.WorkspaceHistory

Ever since ce5aae54035957846baa68f8980218cd11334722 TopicSpace uses the
history implementation of X.H.WorkspaceHistory instead of something
hand-rolled.  This, however, did not go far enough; at this point, we
can deprecate essentially all of TopicSpace's redundant history handling
and explicitly tell users to use the more modular X.H.WorkspaceHistory
instead.
