Project - don't create the empty tag on create anymore

Summary: Fixes T7284. We were initialized the project name to the empty string, which was making things work like a rename, including automagically adding the old slug.

Test Plan: made a project and no more "empty" tag being made. also don't have that bad transaction story anymore.
