Update the signups table, adding signup_id column and drop domain index.

Description Description

This is necessary because WordPress’s pre_schema_upgrade() function wraps table ALTER’s in multisite checks, and other plugins may have installed their own sign-ups table; Eg: Gravity Forms User Registration Add On.
