Title: Fix sandbox #reload! exception with SQLite3

Fixes #11834

Stop connection_pool from disconnecting the connection holding the
sandbox transaction (which should remain open throughout the session).
This bug only occurs with SQLite sandboxes, because only a SQLite
connection requires_reloading.
