Blobifier hard config failure with v2.7.1 in _BLOBIFIER_INIT

[lordofhyphens]

A chunk of checks was commented out of _BLOBIFIER_INIT with as "TODO, need to rethink".

One of the checks was buried in an if/elif . Since it's a check advising to turn on BLOBIFIER_PARK extension if BLOBIFIER is on, I think it needed to be commented out as well. Leaving the check in would at minimum require change the elif clause to if

Fixed in a patch after initial release. Thanks.
