Turn allowAutomaticNext off for tours using the legacy API

That feature is new to the current API.  It occurs for legacy API
tours since the shim uses .next().

However, tours using the legacy API are not expecting it, and it can
cause problems.

This was reported as affecting The Wikipedia Adventure.
