MySQL error after updating to actual version

I've updated my patch from #16 to the latest version. This patch is just commenting out the affected lines. It probably is not solving the issue itself and should be used carefully.

For some reason, the latest version of webform_views 8.x-5.5 is missing this patch.
Without this patch, views throw an error: "SQLSTATE[HY000]: General error: 1116 Too many tables; MySQL can only use 61 tables in a join".
Please include this patch. Thx.

Re-rolled patch from #28 as is for version 8.x-5.5.
