Do not fail cleanup when the session has no default graph.

When Open(t, Options{}) connects to PostgreSQL without a schema or kinds, buildSchema returns nil. The PostgreSQL driver then has no default graph. Close calls ResetGraph, which cannot target a graph, so t.Cleanup fails an otherwise successful test. The previous cleanup ignored that error. Skip graph reset when no graph was configured, while still closing the database. (raw.githubusercontent.com)

Review comment at @integration/harness.go around lines 216 - 217:
Update the Close cleanup flow so it skips ResetGraph when no schema or kinds
configured a default graph, while still closing the database; preserve the
existing cleanupMode behavior for configured graphs.
