Enable/disable xUnit2029 rule

[f-alizada]

Context

After the #10577 is merged the new warnings of xunit analyzers were disabled. The goal is to check each warning and enable or leave as it is with explanation

https://xunit.net/xunit.analyzers/rules/xUnit2029

Goal

The goal is to enable the warning when Assert,Empty is used on the filtered collection.
Instead there is Assert.DoesNotContain(array, condition) could be used.

The pros of using this:

• More readble test's code
• Unified style in tests
