Style issue with triple quotes

[justinmoon]

I was following along with the Ariadne GraphQL server tutorial where we defined this beautiful little snippet representing a "Hello, world!" GraphQL query:

type_defs = gql("""
    type Query {
        hello String!
    }
""")

Black formatted it into this:

type_defs = gql(
    """
    type Query {
        hello String!
    }
"""
)

I'm not sure what the "right thing" is here, but the black formatted version looks much worse to me. It's 2 lines longer and the quotes have mismatched indentation. It's the first time I've had an "ewwww" reaction to black's formatting, so I figured I'd leave you folks some feedback 👍

I'm using black, version 18.9b0

How's it look with 19.10b0?

Let's track this in #256
