hg: perform update after pulling during clone with share (issue5103)

This is a graft of 60adda1a0188 and a4692267bc2d from the default
branch. Combined, they address a bug with pooled shared storage where
an update may not update to the most recent revision when performing
a `hg clone`.

The patches should have been written against the stable branch in
the beginning. I screwed up.

  $ echo 'raise Exception("bit bucket overflow")' > badext.py
  $ abspath=`pwd`/badext.py

  $ cat <<EOF >> $HGRCPATH
  > [extensions]
  > gpg =
  > hgext.gpg =
  > badext = $abspath
  > badext2 =
  > EOF

  $ hg -q help help 2>&1 |grep extension
  *** failed to import extension badext from $TESTTMP/badext.py: bit bucket overflow
