ActivityStream nolonger works if upgrading a legacy system using MyISAM engine and with character set UTF8

Discovered this when upgrading myxwiki.org, the query fails because hibernate cannot create the collection.
Suspected to be this:

There is no migrator to add the activitystream_events_parameters table so it works on new systems but when upgrading, it fails.
