[BUG] No stub generated if derived interface does not contain Refit methods

[daangruijters]

Describe the bug
Refit does not recognize derived interfaces as a Refit-interface, if the derived interface does not contain methods decorated with a Refit attribute.

Steps To Reproduce

1. Create a generic Refit-interface, for example:

public interface ICrudOperations<TEntity> where TEntity : class    
{
    [Delete("/{id}")]
    Task<IActionResult> Delete(long id);

    [Get("")]
    Task<TEntity> Get(long id);

    [Get("")]
    Task<IEnumerable<TEntity>> GetAll();

    [Post("")]
    Task<TEntity> Create(TEntity dto);

    [Put("/{id}")]
    Task<IActionResult> Update(long id, TEntity dto);
}

2. Now create another interface that inherits from this interface:

public interface IOrdersAPI : ICrudOperations<Order>
{
}

3. Now create a client based on the second interface:

RestService.For<IOrdersAPI>(url);

Refit will throw an exception because it does not recognize 'IOrdersAPI' as a Refit-interface.

Expected behavior
Stub will be generated, even if the derived interface does not specify any Refit methods itself.

Should be fixed by the latest code in main. The next 6.0 preview should have the fix, can you please verify with that?

Actually realized it's won't work yet. The generator is looking for methods with and won't see derived types.

Tested and works like a charm, thank you!
