"operationName" should not be part of "variables"

[FabioGimmillaro]

Hi guys,

I just tried to test my graphQL-API with GraphiQL and everything worked fine.

But when I tried to define multiple queries/mutation in one body I got a GraphQLError "Must provide an operation name from: [op1, op2]"

I soon realized that you actually read the operationName out of the variables string I provide for the schema execution.
Wouldn't it be better to add a new argument "operationName" to the execute-function of the schema?

Otherwise I have to inject the operationName into the variables before calling the function.

Greetings,
Fabio
