Fixes: #16292 - Properly restrict GraphQL queries for querys with pk set

• Set name on Schema type to "Query" (required as part of the default resolver generation)
• Change resolver to regular Field with appropriate type
• Set DEFAULT_PK_FIELD_NAME in settings.py to id

[DanSheps]

Added bonus, pycharm find and replace regex for this change:

    @strawberry.field
    def (.*)\(self, id: int\) -> (.*):
        return models\..*\.objects\.get\(pk=id\)

    $1: $2 = strawberry_django.field()

I've replicated all of Dan's changes application-wide and it seems to work well. We still need to add a test for this though.

[jeremystretch]

I've extended the existing GraphQL API tests to check for this.

Also, it seems that GraphQL is logging an exception for requests which query an invalid object ID (but still returning the expected response). I've compensated for this in the test to reduce noise, but it's something we should look into separately.

I'm still a bit leery of the [name="Query") as I'm not sure if it's needed or has side-effects, but in testing I couldn't find any difference it causes so seems okay.
