do not set name field for addresses

[missinglink]

DRAFT WIP

This PR makes use of https://github.com/pelias/schema/pull/364 to remove the duplication of data between the address_parts fields and the name.default field.

Removing the address_extractor stream means that no address layer records will be produced. Prior to this PR we would clone venue records to the address layer, and, in fact, we also had support for accept semi-colon delimited house numbers.

So this PR is still WIP, we'd need to give some more consideration to the impact of the above changes before we could merge this.
