Create User: Return correct status code

[klaerch]

When trying to add a user that already exists the API currently returns the status "bad request". But actually the request is correct, only the response should contain the information, that the user already existed AND return the ID of that user.

Use case: I am using Zapier to add new users. There are several steps in the process:

1. request "add user"
2. request "add that user to space xy"

But Zapier receives "error 400" on the first requests and stops, because it thinks the request was malformed.

I would suggest if there is already a user with the email address or username, we can return an HTTP Error 409 Conflict. Possibly with an output of "Conflicted with user details".

Otherwise I guess you have to do getUserByEmail/Id/Username first and check if the user already exists.

Would this be possible with your Zapier environment?
