Rename regression test to follow issue number convention

The `defaultBunSQLObject` and `constructBunSQLObject` PropertyCallback
functions could crash when the bun:sql module failed to evaluate (e.g.
when globalThis.Array was tampered with, causing "The superclass is not
a constructor" in internal:sql/shared).

Two issues caused the crash:
1. In debug builds, `reportUncaughtExceptionAtEventLoop` was called
   before `RETURN_IF_EXCEPTION`, which cleared the VM exception as a
   side effect of re-entering JavaScript. This caused
   `RETURN_IF_EXCEPTION` to not trigger, falling through to
   `sqlValue.getObject()->get()` with a null object pointer.
2. `RETURN_IF_EXCEPTION(scope, {})` returned an empty JSValue (`{}`),
   but JSC's PropertyCallback mechanism (reifyStaticProperty) calls
   `putDirect` on the result without checking for empty values,
   causing undefined behavior.

Fix: Check for exceptions explicitly after `requireId`, clear the
exception (since PropertyCallbacks cannot propagate exceptions), and
return `jsUndefined()` as a safe fallback value.
