Since we decided to open Human Connection for public registration, we
don't need to create artificial shortage of signups. The original
intention here was too:
1. Grow the network slowly and under control
2. Create an incentive for users to invite their friends
Point 2 is now obsolete, everyone can signup herself. Point 1 is based
on the (seemingly) wrong assumption that there will be a "run" on the
network if we open it for public registration. Our growth was fairly
stable so far.
Apparently, `neo4j-graphql-js` *replaces* the schema partly. When we use
join models like `EMOTED`, `neo4j-graphql-js` puts in a join model with
the two names of the connected types.
FYI: @Tirokk I think we'll never remove or add new badges through
graphql. Instead, we will seed them manually with direct access to the
database. Therefore I removed the respective mutations and also your
tests regarding permissions.
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.
