topic: make topic namespace use string "none" as the default/empty value

The rationale is to not let topic namespaces be confused with neither default
branch nor the actual default namespace value (which is planned to be
configurable, but probably will be local user name by default).

** Testing resolution of orphans by `hg evolve` where an obsolete changeset has
multiple successors **
