title: Inline Data for a Theory doesn't track changes in R# runner
body: <p>I have an Unit Tests like that</p>
  
  <pre><code>[Theory]
  [InlineData("1")]
  public void Should_Fail_Because_Blabla(string value)
  {
    var success =  MyClass.MyStaticMethod(value)
    Asset.False(success, "bla bla");
  }
  </code></pre>
  
  <p>I'm Using VS 2017, xUnit 2.3.1 on a .net core 2.1 assembly and also have R# 2018.1.2 installed.</p>
  
  <p>When I change the the Value of the InlineData, the Data isn't updated in the
  "Unit Test Sessions" window of the R# and running the test, does it with the outdated data.</p>
  
  <p>However if I comment / uncomment the InlineData, works.</p>
  
  <p>Any Idea how to fix the issue, so t hat the actual inline data is taken alsways into considreation?</p>
