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

The new version of xunit that is used right now in the build provides convenient way of reporting the fail.

Goal

The goal is to enable the warning if
Assert.True(false) or Assert.False(true) is met.
And change the usage to Assert.Fail()

The pros of using this:

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