Christoph Herzog 0bf8682daf refactor(backend-api)!: Rename GetCurrentUser, add GetCurrentUserWithNamespaces
Make the GetCurrentUser query only return a plain user without
namespaces.

Rename the current function/query to GetCurrentUserWithNamespaces,
get_current_user_with_namespaces.

This makes more sense , since the namespace query adds quite a lot of
extra work.
