tag: fix uncommitted merge check and error message (issue2542)

This patch corrects the check for tagging on an uncommitted merge. We
should never commit a new tag changeset on an uncommitted merge, whether
or not --rev is specified. It also changes the error message from:

  abort: cannot partially commit a merge (do not specify files or patterns)

to the much more accurate (and terse):

  abort: uncommitted merge

Local tags are ok.

  $ hg init
  $ echo a > a
  $ hg add a
  $ hg commit -m test

Do we ever miss a sub-second change?:

  $ for i in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20; do
  >     hg co -qC 0
  >     echo b > a
  >     hg st
  > done
