Summary:
This removes checking for full access in `onRecord/onRecords` when `includeColumns` is a non-default value. The check had two problems:
1. It relied on the access level being present in the URL query parameters, which doesn't work if the page has redirected. See the discussion in https://grist.slack.com/archives/C0234CPPXPA/p1702576602615509. There seems to be no way to reliably and synchronously check the access level.
2. Calling `onRecords` before `ready` and forgetting to handle an error from the access check meant that `ready` wouldn't be called, so Grist couldn't request the correct access level from the user. I made this mistake and it seems like a nasty footgun.
Ultimately this has no effect on security, as an error will still be raised, but in a place where the widget developer can't catch it. They'll still see an error message in the console, and they can still check the access level reliably using `onOptions`, so I think this is OK.
