[graphql] dont wipe instance in checks test (#26134)

we already wipe in the context fixture 

https://github.com/dagster-io/dagster/blob/master/python_modules/dagster-graphql/dagster_graphql_tests/graphql/graphql_context_test_suite.py#L792
so this just messes up places that change that out

## How I Tested These Changes
