The checkpoint command cycles packfiles if object_count != 0, a sensible
test or there would be no pack files to write. Since 820b931012, the
command also dumps branches, tags and marks, but still conditionally.
However, it is possible for a command stream to modify refs or create
marks without creating any new objects.
For example, reset a branch:
$ git fast-import
reset refs/heads/master
from refs/heads/master^
checkpoint
but refs/heads/master remains unchanged.
Other example: a commit command that re-creates an object that already
exists in the object database.
This fix unconditionally calls dump_{branches,tags,marks}() for all
checkpoint commands. dump_branches() and dump_tags() are cheap to call
in the case of a no-op.
