Title: Migration tweak to fix a failure in switching column types for key

I had an issue running this 0002 migration, until I made this tweak. Still seems to produce the correct field change and index creation.

Looked like it was trying to make the existing text column unique before changing to a character column, which bombed due to the proposed unique index not having a character size.
