Permanent saving of some types

[granit1986]

Several types such as DateTime, byte[] which are different from redis types, were always detected as modified and saved

@slorello89 I don`t understand what it's happened. Local this tests works fine

[slorello89]

@granit1986 - it looks like you are encountering an issue with timezones, I don't think there's anything wrong with thow the code is operating at least insofar as DateTime is concerned. A DateTime is converted to a DateTimeOffset with the local timezone information so it can be converted back and forth to the same DateTime as the server that constructed it was using.

I'm able to revert your changes and still have those tests pass.

@slorello89

Great. Thank you. I think we can leave it like this.

[slorello89]

@granit1986 - my point was that given I'm able to revert your code changes and still have your tests pass, I don't know that this PR is necessary?

[granit1986]

I was hoping that these fixes would make it into the main repository.

[slorello89]

@granit1986 - I understand, but your tests pass against the original code base, so it's unclear what's being fixed by them, it sounds more like you were having a timezone issue with your DateTimes then an actual defect in Redis OM.

[granit1986]

I understand. I will try fix test for new case

[granit1986]

@slorello89 i changed test.
here it is implied that the date update should not occur if the value has not changed
