Fix S2699 FP: Support Moq

[bdovaz]

S2699

Description

The following rule supports several frameworks but Moq is not among them:

https://rules.sonarsource.com/csharp/RSPEC-2699/

As you can see in the examples, it allows to verify for example that a method or event call is made:

But not being an Assert throws this rule as a false positive and forces to do ugly things like Assert.True(true).

Repro steps

Create a minimal example of Moq by taking it from the Readme.md file in repository and see how it throws the false positive of the mentioned rule.
