Activities TypeError: '<' not supported between instances of 'datetime.datetime' and 'str'

[will-moore]

from https://qa.openmicroscopy.org/qa/feedback/91968/

I wonder if this could be caused by some activities being from before and after the change at https://github.com/ome/omero-web/pull/637/files#diff-83195df10aab64309a022de64b165eb4e5b76f4b8ec5fd70a2dbfbbbe02679dbR1201

Probably temporary - Unfortunately no contact details for the QA report

This could have been caused by upgrading OMERO.web without clearing existing sessions.
