topic: only set topic on workingcommitctx if it doesn't already have one

This fix is so obvious, that I wonder, if this is the correct thing to do, why
wasn't it done like this from the beginning. Despite my doubts, all the tests
pass.

Parsing

  $ hg debugparsefqbn foo/bar//user26/feature -T '[{branch}] <{topic_namespace}> ({topic})\n'
  [foo/bar] <user26> (feature)

no double slashes means it's a named branch
  $ hg debug-parse-fqbn foo/bar
  branch:    foo/bar
  namespace: default
  topic:     

Formatting

  $ hg debugformatfqbn -b branch -n namespace -t topic
  branch//namespace/topic

  $ hg debug-format-fqbn -n namespace
  //namespace/

  $ hg debug-format-fqbn -b foo/bar -n user26 -t feature
  foo/bar//user26/feature

default values

  $ hg debug-format-fqbn -b default -n default -t '' --no-short
