How to test

• checkout and run feature/4349/exclude-hearings-from-open-mtg-tab
• Make sure no hearings show up in Open meetings tab
• Make sure Hearings pages made with with incorrect meeting type of 'O', like September 14, 2017 audit hearing, don't show up in Open meeings tab
• Search for Oklahoma democratic party in open meetings tab and confirm results contain those keywords
• Note: in rare instances, Imported html for meetings before May 2017 may have commented-out html that can cause a search result for a keywords that are hidden on the rendered page. Example: search 'hearing ' on open meeting tab and you get a result for March 16, 2016 that does not show the word 'hearing' in the body text (it is in commented html)

Here is the example if incorrectly labeled Hearing in Wagtail:

@johnnyporkchops We seem to be missing two of the public hearings on local. That won't be a problem for production, will it? I'm assuming the production site is ahead of your PR, correct?

[johnnyporkchops]

@JonellaCulmer , Yes, that's expected, your local database would be behind production. If you wanted to update your local database with the latest, I can pair with you on it.
I assume its the two 2021 hearings that were likely added since you have done a local database update.

Works as expected. Thanks so much, @johnnyporkchops
