Drop "New" and "Builder" from the function names, in favor of the top-level resource created. This shortens tests and gives a nice syntax. Since everything is a builder, the prefix and suffix don't add much value and just make things harder to read.
I've also chosen to leave `Do()` as the function to insert into the database. Even though it's a builder pattern, I fear `.Build()` might be confusing with Workspace Builds. One other idea is `Insert()` but if we later add dbfake functions that update, this might be inconsistent.
