* ✅ Fix test with newer graphene
null default values (graphql-python/graphene@03277a5)
no more trailing newlines
* Add ability to pass `execution_context_class` to `GraphQLView.as_view()`
Currently when passing `execution_context_class` like this:
```
GraphQLView.as_view(execution_context_class=CustomContext)
```
you get the following error from `View.as_view()`
```
TypeError: GraphQLView() received an invalid keyword 'execution_context_class'. as_view only accepts arguments that are already attributes of the class.
```
this PR fixes the `hasattr` check in `.as_view`.

Graphiql has a history tool that allows you to save and label favourites, but this version has a bug (fixed https://github.com/graphql/graphiql/issues/750). This change upgrades to the latest version.
operationName is serialized into the query string as a string. When getting the query value for operationName, we need to convert string "null" into None.
