Run drush imports as user=1

Reroll patch.

#12 works fine for me also, D10.1.5 php8.1. It fixed the error 'User %user not allowed to go from state %sid1 to %sid2' from workflow module, as it made migrate as anonymous.

> @Wim Leers, it is on text filters/formats. Full HTML is secured to only admin users. But drush runs everything as anonymous. And my content has a very common thing called a body field and entity validation running as anonymous fails validation. It isn't an issue running from migrate_drupal_ui, as it requires you to run the upgrade as user=1.

Furthermore, with entity types that don't have an owner such as block_content, EntityContentBase::validateEntity() won't do any account switching.
