[PATCH 2/4] rebase: avoid double reflog entry when switching branches

["Johannes Schindelin via GitGitGadget" <gitgitgadget@gmail.com>]

From: Johannes Schindelin <johannes.schindelin@gmx.de>

When switching a branch *and* updating said branch to a different
revision, let's avoid a double entry by first updating the branch and
then adjusting the symbolic ref HEAD.
