rearrange -> rotate -> rearrange CRASH!

see $title, something about log:

!! Something unexpected has happened at 21:02:02-16:13:38

Please file a bug and copy-paste the following:

Traceback (most recent call last):
  File "/app/lib/python3.8/site-packages/plom/client/annotator.py", line 874, in rearrangePages
    rearrangeView = RearrangementViewer(
  File "/app/lib/python3.8/site-packages/plom/client/origscanviewer.py", line 268, in __init__
    self.populateListWithCurrent(current_pages)
  File "/app/lib/python3.8/site-packages/plom/client/origscanviewer.py", line 585, in populateListWithCurrent
    log.error('TODO apply "orientation" of {}'.format(kv["orientation"]))
NameError: name 'log' is not defined

I think this is a regression from my orientation metadata changes recently. Probably just that annotator has no log or some such nonsense.

But urgent b/c I hit it twice when demo'ing Plom this morning.
