GraphQL Schema doesn't support a GraphQL endpoind of / (slash)

Problem

During testing of the GraphQL Schema support in API Security, it was found that an error occured when trying to test GraphQL endpoints that don't contain a path (/). A unit test exists that reproduces the issue GraphQlIntegrationTests.GraphQlPathOfSlash. Currently the test is marked as ignored until this bug is fixed.

Customer impact: Unable to test GraphQL endpoints that have no path.

Workaround: Configure test instance to have a path.
