Schema: merge 1.2.0.sql upgrades into 1.1.1.sql

Initially, we planed a 1.2.0 release instead of 1.1.1 so over time, both schema
upgrade files appeared. Merge them to clean up in preparation for the 1.1.1
release.

Changes were generated using these commands:

    { echo; cat schema/mysql/upgrades/1.2.0.sql } >> schema/mysql/upgrades/1.1.1.sql
    { echo; cat schema/pgsql/upgrades/1.2.0.sql } >> schema/pgsql/upgrades/1.1.1.sql
    git rm schema/mysql/upgrades/1.2.0.sql
    git rm schema/pgsql/upgrades/1.2.0.sql
