Fix the issues reported by phpcs

Above errors/warnings has been fixed.

Hi

The patch is applied zero phpcs errors in my local.
Then I created MR for this patch.

Thanks.

Removing credit for the MR when there was already a patch.

@samit.310@gmail.com, whilst I appreciate coding standards patches, my policy is not to give credit to contributors who already have credit for coding standards patches. Coding standards patches are great for folks finding their feet with the mechanics of contribution, but more experienced developers can help in other ways. Please refer to tip 2 on https://www.previousnext.com.au/blog/5-simple-tips-increase-your-drupal-... for more information. As I can see from your profile that you have a number of phpcs credits already, I've decided to remove your credit in this instance.

Can we replace this with a comment - e.g.

'Create a user with no value for test_field' to explain why we need it?
