Added error handling and empty array check

This would improve issue for #253

This contains fix for issue #256

Hey @zulander1 thanks for opening this, couple things:

1. Use Enviornment.Newline rather than carriage returns
2. Add a test in SearchTest.cs - something like this should suffice:

[Fact]
        public void TestNullResponseDoc()
        {
            int? nullVal = null;
            var nullResult = RedisResult.Create(nullVal);
            var res = new RedisReply[] { 1, $"foo:{Ulid.NewUlid()}", new (nullResult) };
            
            var query = new RedisQuery("fake-idx");
            _mock.Setup(x => x.Execute(It.IsAny<string>(), It.IsAny<string[]>()))
                .Returns(res);

            var result = _mock.Object.Search<Person>(query);
        }

        }

Done, applied the correctoins

@slorello89 , I am not sure why the building is failing on test Redis.OM.Unit.Tests.RediSearchTests.SearchFunctionalTests.TestSave, working on my local, can you help ?

LGTM 👍 - issue with the tests were related to another PR and how that interacted with the search tests.
