Python: Ensure old dataflow queries are not used

There seems to have been some cases where the old ones have been picked up
instead of the new ones. At least I spotted _one_ case where this happened, in
an internal actions run.

I'm not sure how to actual debug this, so just removing all the tags that could
make these queries to become picked up :|
