topic: properly decode topic and topic namespace after reading from disk

Looks like we forgot that the bytes read from disk should be converted to the
local encoding. The way it's done in this patch is how branch is handled in
core.

  $ . $TESTDIR/testlib/topic_setup.sh

Code logically equivalent to the following is used in Zsh to show the branch
and topic (if set) in the prompt. If the format of the files is changed in a
way that it breaks the test, a mail should be sent to [e-mail].

  $ get_branch_like_zsh() {
  >     branchfile=".hg/branch"
  >     topicfile=".hg/topic"
  >     if [ -r "${branchfile}" ] ; then
  >         r_branch=$(cat "${branchfile}")
  >     fi
  >     if [ -f "${topicfile}" ] && [ -r "${topicfile}" ] && [ -s "${topicfile}" ] ; then
  >         IFS= read -r REPLY < ${topicfile}
  >         r_branch=${r_branch}:${REPLY}
  >     fi
  >     echo $r_branch
  > }
