Fix upgrade script executing against master instead of PerformanceMonitor (#828)

01_widen_version_columns.sql (PR #722) was missing USE PerformanceMonitor and
SET options that every other upgrade script has. The installer connects to master,
so the script's OBJECT_ID check resolved against master, found nothing, skipped
both ALTERs, and reported success while leaving columns at nvarchar(255).
