Added a new test case, apply_to_marketplace_without_fields_shouldnt_work, to the Gated Marketplace pallet. This test verifies that an application without any fields leads to the FieldsNotProvided error. It enhances the test coverage for the apply function, ensuring it robustly catches instance where application fields are not provided as intended.
