What happened?

Description

Running the resave/entries command to clear a field type of entries does not clear the field.

1. Tested running the same command but clearing a plain text field and it worked fine.
2. Tested running the same command without the --site option and the createdBy field is still not cleared.

Steps to reproduce

1. In a es_MX site with a site handle of MX create a field called createdBy with a field type of Entries min and max relations of 1, show the site menu ticked, and manage relations on a per-site basis ticked.
2. Create an entry and select an entry inside the createdBy field and save the entry.
3. run php craft resave/entries --site mx --set createdBy --to=:empty:

Expected behavior

createdBy should be empty.

Actual behavior

createdBy is not empty and still retains the old value.
