certdb/sql: remove uses of github.com/stretchr/testify/require

This was the only location where this assertion library was used; all
other code in this repository used Go's stdlib for assertions. The
remaining uses in this package could be replaced without too much
trouble, which allowed for the dependency (including its indirect
dependencies) to be removed altogether.
