Ok, we have no control what parameters are passed to the cypher query
generated by `neo4j-graphql-js`. So I'm re-using the `filter` param.
If the `$filter` param is `{}` then we can use COALESCE to turn that
into empty array. Ugh.
Wow this took me the entire day: If you run `createServer` multiple
times, more and more middlewares get added to the schema. That's why
the test would create 2^n notifications for n times you called
`createServer`. This is related to the following bug:
https://github.com/prisma/graphql-middleware/issues/63
@mattwr18 I prefer (I believe it's even best practice) that a delete
mutation should return the deleted object. If you run the delete
mutation again, it should return `null` because there is no object like
that anymore. That way the client knows if a delete mutation has changed
any state in the database.
Also I fixed another bug in the resolver. If your graphql mutation looks
like this:
```gql
mutation {
RemovePostEmotions(to:{ id:"p15"}, data:{emotion: angry}) {
from {
id
name
}
to {
id
title
}
emotion
}
}
```
Then you get errors because your resolver does not return the name for
the user or the title for the post anymore. Just use spread operator...
and it's fixed.

Fix youtu.be not being embedded

`provider.provider_url`.

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. ;(
