Unsupported properties are being deleted on updates

[jamietanna]

When a post contains properties that Micropublish doesn't support, such as featured, the Micropublish UI doesn't render that property.

I think that's quite reasonable, as there's not necessarily a point showing a property we don't understand.

However, when sending an update request, it appears that Micropublish is deleting the properties it doesn't understand, rather than just ignoring them.

Is that intentional?

Example Post

[`https://www.jvt.me/posts/2021/03/24/chef-cookbook-gem-metadata/`](https://www-api.jvt.me/micropub?q=source&url=https://www.jvt.me/posts/2021/03/24/chef-cookbook-gem-metadata/): ```json { "type": [ "h-entry" ], "properties": { "summary": [ "How to source your Chef Gem dependencies from your Chef cookbook's `metadata.rb` instead of duplicating them between files." ], "code-license": [ "Apache-2.0" ], "featured": [ "/img/vendor/chef-logo.png" ], "name": [ "Managing Your Chef Gem Dependencies More Easily in your `Gemfile`" ], "prose-license": [ "CC-BY-NC-SA-4.0" ], "published": [ "2021-03-24T13:42:37+0000" ], "category": [ "blogumentation", "chef", "ruby" ], "post-status": [ "published" ], "content": [ "..." ] } } ```

Update Request Body

```json { "action": "update", "delete": [ "code-license", "featured", "prose-license" ], "replace": { "content": [ "..." ] }, "url": "https://www.jvt.me/posts/2021/03/24/chef-cookbook-gem-metadata/" } ```

That doesn't sound right. There should be a "known properties" list but that may not be working correctly. I'll take a closer look.

@jamietanna I have a PR #68 and a temporary Review App at https://mpubl-pr-68.herokuapp.com with a fix. Can you see if this now works successfully with your server?
