Make tests work with GraphQL-core 3.2.0rc2

[Cito]

This fix aligns to some changes in GraphQL-core 3.2 which reflect changes in GraphQL.js 16:

• type resolvers must return only names
• doesn't print trailing newlines any more
• different wording of some error messages

Closes #1406 ? Our CI caught another faulty import with 3.2 btw: https://github.com/graphql-python/graphene/pull/1415/files

I made a pull request built on top of this pull request, hopefully fixing the remaining issues: #1417

[SuperSandro2000]

This can be closed with the 3.1.0 release.

[ddelange]

yes, superceded by #1421
