convert: avoid updating tags when there is nothing new

Previously, when converting from a mercurial repo there would be an extraneous
commit at the end of the convert process that would rewrite tags. Now, we check
if there are any new tags before doing this rewriting.

  $ "$TESTDIR/hghave" symlink || exit 80

  $ origdir=`pwd`

  $ hg init repo
  $ cd repo
  $ ln -s nothing dangling

avoid tar warnings about old timestamp

  $ hg ci -d '2000-01-01 00:00:00 +0000' -qAm 'add symlink'

  $ hg archive -t files ../archive
  $ hg archive -t tar -p tar ../archive.tar
  $ hg archive -t zip -p zip ../archive.zip
