Changelog handling: No not check out last push any more during raw import

We now get the changelog with mergeinfo_getclogp (which just fetches
the changelog blob).  This working tree is not used for anything else,
and is deleted at the end of the function.  So there is no need to
switch branches.

There should be no overall behavioural change.
