Remove confusing code comments and obsolete code
I discovered that the behaviour of no duplicate notifications being send
out is caused by the frontend: When the editor reads html from the
backend, it will parse hashtags and mentions as ordinary links, not as
their respective nodes during editing. Also, we don't have to worry
about duplicate ids being found: The cypher statement will implicitly
suppress duplicate notification nodes for the same user.
So let's remove the code to avoid confusing the next developer.

Test editor.getHTML()
I do this because I'm not able to test the content of `this.editor` from
a wrapper of `vue-test-utils`. If I call `this.editor.getHTML` directly
and use it as a computed property `renderedContent` to populate a `<div
v-html="renderedContent" />` this will not work for the embeds. So, my
current best bet is to test the editor object isolated from a real
component. ;(

This commit takes all backend changes for signup and invite feature. I
was working on these features and removed the generated mutations for
type user along the way.

I think I just fixed a randomly failing test (so-called "flaky" test).
After an update of `neo4j-graphql-js` I wondered why the
`TagsAndCategories.feature` test failed consistently. It turns out the
table that you can see in the test is ordered by the "Users" column:
| | Name | Users | Posts |
| 1 | Democracy | 2 | 3 |
| 2 | Ecology | 1 | 1 |
| 3 | Nature | 1 | 2 |
So there is a tie between row 2 and row 3. It seems that on version
2.4.0 the backend would return those rows in arbitrary order and now it
returns them in a deterministic order, thus failing the test every time.
Therefore I changed the test setup and I believe this should also make
the build more robust now.
