Publish on field changes to required state when revision is set for content type

Found that this error occurs due to the overridden massageFormValues() in /src/Plugin/Field/FieldWidget/TimestampDatetimeNoDefaultWidget.php

After removing this method, the error is not reproducible.

Created the patch accordingly. Please review.

Hi bala_28,
Just pointing out some things here, on how to post issues and how to get support from the maintainer

1. If you want a patch to get tested, please run the tests
2. If you want a patch reviewed then set the status to 'needs review'
3. Just saying "created patch" and demanding "please review" is not likely to make me or other maintainers look kindly towards helping you
4. However, I have looked at the patch and it simply deletes a method from the code. Do you really think that this is a solution that would be accepted?

Patch #3 is invalid and it updates the current time on submit.
