Merge #110005

110005: externalconn/testutils: fix a mistake in SetSQLDBForUser r=stevendanna a=knz

All commits but the last are from #110004 (review only the last commit here)

Prior to this patch, this method was incorrectly swapping a SQL
connection to the secondary tenant for one to the system tenant.

This patch fixes it.
